ExxonMobil Point Thomson Expansion Plan Approved

first_imgThe Division of Oil and Gas had previously approved ExxonMobil’s plan for continued liquid condensate production from Point Thomson, but declined to approve the expansion-related plan. The Governor suggests that interest in North Slope to tidewater gasline project has grown immensely in the last 45 days due to the historic Joint Development Agreement between the State of Alaska and Chinese concerns. Facebook0TwitterEmailPrintFriendly分享The State of Alaska has approved ExxonMobil’s plan to engineer the expansion of the Point Thomson project on the North Slope, with state and company officials calling it a positive step to achieve major gas sales and increase oil production.  Governor Bill Walker says that the expansion strengthens the viability of the Alaska LNG Project. Story as aired:Audio PlayerDorene-on-exxonmobil-pointthomson-expansion-plan-approved.mp3VmDorene-on-exxonmobil-pointthomson-expansion-plan-approved.mp300:00RPdcenter_img The division asked for additional information on August 29. ExxonMobil responded to the Division’s concerns with new information in mid-October. In a written release, Walker notes that State approval of the Point Thomson to Prudhoe Bay pipeline demonstrates the commitment of the Point Thomson working interest owners to move gas from Point Thomson into Alaska Gasline Development Corporation’s 800-mile pipeline. Walker says the expansion project is expected to increase oil production out of Point Thomson by 50,000 barrels per day.last_img read more

Is highspeed rail in the US ever going to happen

first_img Speeding to the future The myriad benefits of high-speed rail go far beyond the strict monetary alternative to cars and planes. For one thing, most high-speed trains are electric, and as energy generation moves away from fossil fuels, this means rail becomes significantly greener than airplanes or cars — which is why Democrats like Ocasio-Cortez included it as part of the Green New Deal. Then there are the benefits to the communities along the route, and the jobs created during construction and during use. These benefits are something many other countries have seen, not least China, which in 10 years has gone from essentially no high-speed rail, to more high-speed rail than the rest of the world combined. No doubt these are expensive projects, and historically, only public money and support has made them possible. It will be interesting to see, as the projects above progress, if that’s still the case or if private investment is indeed possible. Best case, they all come to fruition and there will be multiple options for cities and states to add high-speed rail. Worst case? They don’t, or the government has to nationalize them (again). As a big fan of trains, I’m obviously hoping for the former. Count me in for a ride on opening day on each and every one. Share your voice Aug 6 • Trump says he’s watching Google ‘very closely,’ slams CEO Sundar Pichai California Both alphabetically and monetarily, this is the first project we should discuss. Running, in theory, from Northern California to Southern, linking Sacramento and San Francisco to Los Angeles and a few points in between, the California High Speed Rail is already well over budget and behind schedule. Despite my love for high-speed rail, and being a California resident, I was never impressed or optimistic about this project. Having now researched it significantly more for this article I’m… well, more neutral I guess. The pros probably outweigh the cons, mostly.The issue is there are lots of easily identifiable negatives. High-speed rail detractors love to point this project as a glowing example of why the whole idea of high-speed rail is bad. I suppose that’s true of any new rail project, and more so with this one given how expensive it’s become. On the negative side, even at the very high speeds the project is hoping for, it will still take 2 hours, 40 minutes to get from Union Station in LA to downtown San Francisco. It’s only 1.5 hours to fly, so even considering travel to and from airports, that’s nearly a wash. It’s hard to believe they’ll be able to keep ticket prices low enough to compete with airfare, which is often around $60 (roughly £45 or AU$85) each way. California HSR Authority says they’re aiming for an average price of $93 to get from San Francisco to LA, in today’s dollars. This is about 50 percent higher than a flight, but still in the “ballpark.” Personally I’d pay an extra $30 not to fly, and hopefully others will find the premium acceptable too.  Now playing: Watch this: Tags 29 Photos Aug 6 • President Trump wants social media to catch shooters before they strike. It’s going to be hard For more about why it’s so challenging to have higher speeds on this route, and really why high-speed trains are difficult throughout the US, check out this previous explainer about why US trains are so complicated. Texas The Texas Central Railway is another private venture, this time aiming to connect Dallas and Houston in under 90 minutes. Driving would take at least 3.5 hours. The most interesting aspect of this project is the rolling stock: Japanese Shinkansen trains. Specifically, a variant of the N700 Series already in use throughout Japan. Most recently, the TCR has selected Spain’s Renfe to be the train operator (PDF). Initially it’ll offer technical advice on design and construction of the system, then once it’s up and running, it’ll “run the trains; maintain system components, such as the engines, signals and other equipment; oversee ticketing, passenger loyalty programs and other services.”It’s hoping for departures every 30 minutes, a top speed of 200 mph, ticket prices lower than airfare, and to open in the mid-2020s. Since, barring unforeseen delays, that will beat California’s high-speed rail by years, this will likely be the first “true” high-speed rail system in the US by any definition.   Railroads need land, however, and so far Texas Central is having problems procuring it. The project is involved in a legal battle that could prevent it from being able to conduct surveys and acquire property. Referring to the problems, a Texas Central representative told CNET “Texas Central disputes that, saying it is having increasing success in securing land options.” See All Are US trains really that bad?

France has the TGV. Spain has AVE. China has more high-speed rail than the rest of the world combined. America has… the Acela Express. All 16 stops of it in one section of the country. It reaches its top speed of 150 miles per hour (241 kph) just for a few minutes in one short section, and even that speed is pokey compared to other countries. The Shanghai Maglev reaches 268 mph.But things are changing. Despite significant uphill battles, high-speed rail is coming to other parts of the country. Even the Acela is undergoing improvements that should make the service faster and more convenient. And high-speed rail is one of the principal pillars of the Green New Deal drafted by liberal House Democrats, including Alexandria Ocasio-Cortez. It proposes to overhaul the “transportation systems in the United States to eliminate pollution and greenhouse gas emissions from the transportation sector as much as is technologically feasible,” with high-speed rail as one of the main investments. This article doesn’t speculate on lofty goals like that. It’s not about proposed dream projects, like maglevs and hyperloops, nor is it a list of feasibility studies or “hey, we should check out high-speed rail” legislative initiatives. Instead, I’m going to tackle actual projects either in progress or seemingly about to begin. How high is high-speed? The answer to this question isn’t as obvious as it seems. Title 49, subsection V, Part D, Chapter 261(c) of the US code says “sustained speeds of 125 mph or greater.” Other countries would call that “adorable” and “200 kph.” Even other portions of the US government say 150 mph or greater. For our purposes, we’ll go with anything above 125. This is faster than traditional trains, and given the limitations of the tracks throughout the US, a pretty reasonable increase in speed. Also, an article just about US trains capable of over 150 mph would be super short. Other parts of the country are working on improving their “regular” rail so that it’s a bit faster, like Chicago and elsewhere, but that’s for another article. Nevada (and California) A rail link between Los Angeles and Las Vegas has been in the works, on and off, for years. A company called XpressWest got the farthest in the process, and in September it was purchased by Brightline (yep, same one). This is another hard sell, since the current plans only get them from Las Vegas to Victorville. Victorville is Los Angeles as much as Philadelphia is Manhattan. So your average LA resident would need to get to Victorville, nearly two hours by car, then board a train for Brightline’s estimate of two hours to Las Vegas. A flight takes just over an hour, or alternately, it’s a fantastic drive in the same amount of time. There are other desert cities near Victorville, of course, so the trains probably won’t be empty. But as you can probably guess, the idea is to link up to the California regular and eventual high-speed rail network and go all the way to LA’s Union Station. It expects to begin construction this year, with initial service in 2022. Seems optimistic, but I wish it luck.Though no rolling stock has been decided yet, it wouldn’t be surprising if XpressWest plans to use Siemens Chargers since that’s what Brightline is using in Florida, and Siemens is already building a bunch in its California plant for Amtrak’s Pacific Surfliner route. Northeast Corridor (New England, New York, New Jersey, Pennsylvania, Delaware, Maryland and DC) The Acela Express was America’s first, and arguably only, high-speed rail. I say “arguably” because in most parts of the world a top speed of 150 mph, and average speed less than half that, hardly qualifies as “high-speed.” It connects Boston to DC with 14 stops along the way, including New York and Philadelphia. The speeds are almost entirely due to limitations on the tracks and other infrastructure, which is why Amtrak has extensive plans for upgrading the tracks it owns, as well as working with states along the route to improve the non-Amtrak sections. The Acela trains were always far more capable than the tracks they were on, so even seemingly small improvements like raising speeds on a 30 mph section to 50 mph will reap big benefits overall. Many of the improvements will also benefit standard rail service in the area as well. Amtrak is also getting new trains, due in service in 2021. These high-tech models from Alstom are capable not just of higher speeds, but have better tilt capabilities, so they’ll be faster on the slower sections compared to the current trains. If the infrastructure improvements go as planned, new top speeds of 186 mph will be possible on some segments of the route.

Since traveling on these trains would mean fewer cars on the road and fewer passengers on airplanes, the reduction in greenhouse gas emissions should be sizable. With work progressing in the, admittedly easier, Central Valley sections, I’ll be curious to see how this plays out over the next decade(s). Especially since our new governor is far less enthusiastic for the project than our previous governor. Regardless of what happens with the overall project, numerous improvements to the rail infrastructure throughout the state are already underway and will be highly beneficial. Florida Florida has the only private passenger train company in the US: Brightline. In November 2018 it announced it was rebranding as Virgin Trains USA, after Virgin took a minority stake. Hopefully that will turn out better for everyone than what happened on England’s East Cost Main Line. Florida had initially received federal grants to create more high-speed rail, but then governor Rick Scott rejected them in 2011. Some of this route was developed into Brightline. Brightline/Virgin Trains USA currently connects Miami to West Palm Beach, but is too slow to qualify as high speed. However, it’s working on expanding its system north, connecting to Orlando airport via Cocoa. Part of this route will have new tracks on a new right-of-way, allowing speeds up to 125 mph. It uses Siemens Chargers, which we checked out extensively when they were unveiled for the Pacific Surfliner route in Los Angeles. Along with other funding, it’s going public to help get the money it needs. The company has plans to connect to Tampa eventually as well. reading • Is high-speed rail in the US ever going to happen?

The surprising reason Meghan Markle is avoiding the public before giving birth

first_imgMeghan MarkleGetty ImagesMeghan Markle is set to give birth any day now. But the details of her birthing schedule, as well as her labour, are being kept tightly under wraps. The Duchess of Sussex has been on maternity leave for a while.Meghan Markle has kept away from the cameras and the public eye as she prepares to give birth to baby Sussex. Reportedly where Meghan will give birth is still not confirmed, with some believing she will opt for a Windsor hospital over London’s Lindo Wing, where both Kate Middleton and Diana had their children.Meghan has also opted out of posing on the hospital steps after giving birth, which has caused quite an uproar among fans and Royal observers. Childbirth expert Katharine Graves has revealed why Meghan Markle probably won’t be seen in public until after the royal baby is born.She told Express.co.uk: “Towards the end of the third trimester, a mum’s natural instinct is to slow down.” Meghan MarkleGetty Images”Her body needs to produce as much Oxytocin (an essential birth hormone responsible for softening and ripening the cervix, kickstarting labour and ensuring mums contractions are working their very best) as possible.”Privacy is paramount for Meghan Markle during the birth of her child and it seems that her concerns are well-founded. Ms. Graves added, “If Meghan is following a more natural route, then it is possible she will be observing the fourth trimester which is where for the first month, mum keeps baby close to her by babywearing for example, bed sharing and breastfeeding, mimicking the babies life in utero, as this is shown to be beneficial for a newborn in terms of brain development and confidence.”Meghan Markle and Prince Harry have moved to Frogmore Cottage to prepare for the arrival of the Royal baby.last_img read more

Its Costing More To Park At Some Galveston Beaches

first_img Share X 00:00 /01:07 Listen Galveston Park Board The entrance and pay station to Stewart Beach in Galveston.The old rate was $8.00 a day to park at Galveston’s East Beach and Stewart Beach. Now visitors will have to shell out a little more. The new parking rates are $12.00 on weekdays and $15.00 on weekends. Spokeswoman Mary Beth Bassett says the Galveston Park Board wants to raise funds for long-term improvements from parking fees that have stayed the same since 2004.“We want to become more of a regional and national destination,” Bassett says. “And we think that raising the bar will get us to that point.”But to get there, Bassett says need to do a lot of work. They’d like to make about $40 million in upgrades over the next ten years. That includes things like new pavilions and boardwalks. They also have to bring in sand to fight beach erosion.   “So it’s going to be a slow process but we have a plan in place and we know where we can start,” Bassett adds. “We have short-term goals and long-term goals laid out. And as our revenue increases we’ll be able to make incremental changes and improvements.” Bassett says the parking prices will drop after Labor Day to $10.00 on weekdays and $12.00 on weekends.center_img Galveston Master Plan To embed this piece of audio in your site, please use this code:last_img read more

House Tweak To Houston Pension Bill Could Buy Firefighters Fund More Time

first_imgBob Daemmrich for The Texas TribuneRetired Houston firefighters and police officers packed the Texas House gallery on May 8, 2017, as they await debate on a municipal pension bill that would affect their retirement payouts.The Texas House gave early approval Monday to a bill that would reform Houston’s three problematic pension funds, which have caused financial woes and spurred political battles for years.The 112-28 vote for Senate Bill 2190 came after lawmakers made some key changes to the bill, including a provision that could let the firefighter pension fund bear a smaller burden for shoring up billions in shortfalls. But State Rep. Dan Flynn, R-Canton, who authored the House version of the bill, worried that the Senate may not like the changes. “This is an amendment that could very well derail the bill,” Flynn said Monday from the House floor.Meanwhile, firefighters who could benefit from one of the amendments remained cautious after the bill’s preliminary vote.“We have to see how the rest of the process unfolds,” said David Keller, chairman of the Houston firefighter pension fund.SB 2190 would cut some retiree benefit features, increase some employee contributions to funds, and infuse the police and City Hall employee funds with $1 billion, which the city plans to finance through bonds.Firefighters opposed the bill, which still needs a final vote in the House, because it cuts some of their retirement benefits more than they anticipated when their fund is not in nearly as bad of shape as the police and municipal funds. City officials, though, said firefighter benefits were more generous than police and municipal benefits and were too costly to taxpayers. State Rep. Dan Huberty, R-Houston, successfully got his House colleagues to amend the bill so that the firefighter pension fund has an opportunity to lower what its members give up in order to help close a large funding gap.For months, city and state leaders have accused the firefighter pension fund of withholding actuarial data that would prove it could shore up its shortfall with fewer cuts to members’ benefit features. In the absence of such data, city leaders and state lawmakers put together SB 2190 and a House companion — authored by Flynn — that the firefighters opposed.Keller said the retirement system wants to protect individual members’ information and has offered the city data under licensing agreements that included confidentiality provisions. He said he was surprised that became an issue on the House floor considering all firefighter salary information goes through City Hall.“They know what each of us makes,” he said. “There’s nothing surprising in our data we hold.”Huberty’s amendment will give the firefighter fund a deadline to provide the data to the city. It passed 90-42 over the objections of Flynn, who said the firefighter fund had months to help reach a compromise and that such a change could sink the bill when it goes back to the Senate. “At this point it’s really too late to change the critical aspects of this bill,” Flynn said.When the amendment passed, applause broke out from the House gallery above, where scores of Houston first responders had gathered to watch the vote. “I’ve presented many bills this session, and I’ve never said it’s too late,” Huberty said. Flynn’s companion bill was slated to be voted on by the full House on Monday. Instead, Flynn put forward the Senate version, which includes provisions requiring future employees to be switched to a different kind of retirement system if the current funds’ shortfalls exceed certain thresholds in the future.Houston Mayor Sylvester Turner and the city’s police and fire chiefs had warned of first responder shortages if legislation overhauling the pension funds didn’t pass this session. Lawmakers supporting SB 2190 said several times Monday that if a bill didn’t come from the Legislature, the pension funds would fail. State Rep. Dwayne Bohac, R-Houston, also successfully amended the bill to prevent changes in the bill from affecting current retirees. And state Rep. Mike Schofield, R-Katy, tacked on an amendment that would nullify benefit cuts the pension funds agreed to if Houston voters don’t sign off on a plan to infuse the police and municipal retirement funds with $1 billion in pension obligation bonds.Flynn opposed Schofield’s amendment, saying it could have unintended consequences. Yet he almost immediately allowed it to be added onto the bill.“I’m going to go ahead and accept it at this time and we’ll deal with it later,” he said. After the vote, Flynn said it was “good news” that the majority of his House colleagues want to fix the pension systems. But he also wished some of the changes hadn’t been made. He called Huberty’s amendment a “campaign speech” and again criticized firefighter pension board members.“They’ve refused to negotiate,” Flynn said. “They’ve never worked with us in good faith.”Keller said Monday that he didn’t know whether the firefighter pension board would vote to release the data referenced in the amendment.“We’re still working on that,” he said. “I’m just one vote on the board, and the rest of the board will have to have that discussion.” Sharelast_img read more

Conservatives To Hold Rally Against Socialism In Sugar Land

first_img Listen Karen MacWilliamConservative activists are holding a “Stop Socialism” rally in Sugar Land this coming Monday. The event will feature some of the biggest names in Fort Bend County Republican politics, with confirmed speakers including Congressman Pete Olson and former House Majority Leader Tom DeLay.“I decided at a certain point, I just couldn’t take it anymore,” said event organizer Karen MacWilliam. “We just need to secure our border. We need to support [President] Trump. What he’s gone through in the last couple of years…”The focus of the rally is on national issues, including immigration and health care. But Shapnik Khan, a Fort Bend Democratic activist, sees the event as having local implications. He points to the online trolling of county Democratic officials as alleged socialists.“Our newly elected county judge, KP George, was under a smear attack,” Khan said. “Same with our Fort Bend County DA [Brian Middleton] was under attack as well, because of their color, because of their stand with the progressive mindset.” County Judge George is Indian-American, while District Attorney Middleton is African-American.The rally will take place Monday, April 15, from noon to 2 p.m. at Sugar Land Town Square.

Atlanta Illustrator Marcus Williams Brings Diversity to Baltimore ComicCon

first_imgIllustrator Marcus Williams.The annual event known as Baltimore Comic-Con is an opportunity where a cult of artists, creators and writers come together to not be judged. Marcus Williams, an Atlanta, Georgia based illustrator is one of those unique individuals. His work is a representation of a diverse outlook on life.At Baltimore Comic-Con, you get a chance to dress like your favorite fictional character, or even as your alter-ego, in a no-judgment zone.Williams, 34, is a single Black father of two from San Diego, California, who currently resides in Atlanta. He once attended The Art Institute of Atlanta, but soon put his college life on hold to follow his dream as an illustrator. For the past 16 years he has been a professional freelance illustrator for comics and children’s books. In addition, he creates his own original characters. “My life has become drawing…that’s all i do,” said Williams in an interview with The AFRO. “I’m pretty much drawing all the time. When I’m eating, when I’m sleep and when I’m spending time with my kids”Williams added: “I illustrate things that I am passionate about. It’s just me drawing what I feel is cool, or what I wish I could see.”Williams maintains a blog at marcusthevisual.tumblr.com. One of Williams’ works on his blog is a comic he created called “Black Panther & Storm Heritage.” While not officially sanctioned by Marvel, the owner the Black Panther intellectual property, Williams’ creates his own story where the two main characters, who have a child and get divorced in the licensed comic book, stay together.“Those writers made them get a divorce, so I wanted to create a fan fiction that portrayed them still together,” said Williams. “It’s just the imagery. The imagery of showing a super hero black family that is powerful.”Williams is currently working on a comic called “Super Natural,” and “Super-Natural Boy.” No date is set for Super-Natural Boy yet, but his newest comic book called, “Super Natural Book 1,” will be published on September 28.“She’s going to deal with the police, she’s going to deal with the government, she’s going to deal with the media,” said Williams. “She’s new to our culture here in America, but since she’s powerful she’s going to be able to handle those entities much differently. I want to speak to that frustration.”This will not be Williams first time at the Baltimore Comic-Con convention. He will be drawing cats for guests and fans as he’ll turn their cat into a “hero cat” based off his illustrations he does for creator and writer, Kyle Puttkamer, called “Hero Cats of Stellar City.” The book allows an extensive group of cats with abilities to save their city as each cat gives off a distinct personality. “There’s not a lot of cat comic books out there…but there is a huge, huge, huge eagerish market for them, said Williams.”Williams also said: “We really don’t have to sell cats. People walk by our stand and say “Omg, hero cats!” Fanatics love cats already…we really don’t have to work too hard.”For more on “Hero Cats Of Stellar City” go to herocatscomic.com.

The path to perfection Quantum dots in electricallycontrolled cavities yield bright nearly

first_img © 2016 Phys.org , Nature Communications Researchers develop ideal single-photon source Figure 1. a, Schematic of the sources: a single semiconductor quantum dot, represented by a red dot, is positioned within 50 nm from the center of the cavity, which consists of a 3 µm pillar connected to a circular frame through 1.3 µm wide waveguides. The top electrical contact is defined on a large mesa adjacent to the circular frame. By applying a bias to the cavity, the wavelength of the emitted photons can be tuned and the charge noise strongly reduced. b, Emission map of the device: the strong signal coming from the quantum dot located at the center of the cavity demonstrates the precise positioning of the quantum dot in the cavity and the enhanced collection efficiency obtained by accelerating the quantum dot spontaneous emission.

The area of the peak at zero delay allows measuring the photon indistinguishability: it should be zero for fully indistinguishable photons. We test here two configurations: the coalescence of photons with orthogonal polarization (fully distinguishable – blue curve) and the coalescence of photon with the same polarization (red curve). The disappearance of the zero delay peak in the latter case show the near unity indistinguishability of the emitted photons. b, Graph summarizing all the source characteristics as a function of excitation power: brightness (probability of collecting a photon per pulse – red – right scale), autocorrelation function g(2)(0) (characterizing the probability of emitting more than one photon – blue – left bottom scale), indistinguishablity M (purple – left top scale).

Explore further , Optica , Nature Nanotechnology , Nature Dr. Pascale Senellart and Phys.org discussed the paper, Near-optimal single-photon sources in the solid state, that she and her colleagues published in Nature Photonics, which reports the design and fabrication of the first optoelectronic devices made of quantum dots in electrically controlled cavities that provide bright source generating near-unity indistinguishability and pure single photons. “The ideal single photon source is a device that produces light pulses, each of them containing exactly one, and no more than one, photon. Moreover, all the photons should be identical in spatial shape, wavelength, polarization, and a spectrum that is the Fourier transform of its temporal profile,” Senellart tells Phys.org. “As a result, to obtain near optimal single photon sources in an optoelectronic device, we had to solve many scientific and technological challenges, leading to an achievement that is the result of more than seven years of research.”While quantum dots can be considered artificial atoms that therefore emit photons one by one, she explains, due to the high refractive index of any semiconductor device, most single photons emitted by the quantum dot do not exit the semiconductor and therefore cannot be used. “We solved this problem by coupling the quantum dot to a microcavity in order to engineer the electromagnetic field around the emitter and force it to emit in a well-defined mode of the optical field,” Senellart points out. “To do so, we need to position the quantum dot with nanometer-scale accuracy in the microcavity.”Senellart notes that this is the first challenge that the researchers had to address since targeting the issue of quantum dots growing with random spatial positions. “Our team solved this issue in 20081 by proposing a new technology, in-situ lithography, which allows measuring the quantum dot position optically and drawing a pillar cavity around it. With this technique, we can position a single quantum dot with 50 nm accuracy at the center of a micron-sized pillar.” In these cavities, two distributed Bragg reflectors confine the optical field in the vertical direction, and the contrast of the index of refraction between the air and the semiconductor provides the lateral confinement of the light. “Prior to this technology, the fabrication yield of quantum dot cavity devices was in the 10-4 – but today it is larger than 50%.” The scientists used this technique to demonstrate the fabrication of bright single photon sources in 20132, showing that the device can generate light pulses containing a single photon with a probability of 80% – but while all photons had the same spatial shape and wavelength, they were not perfectly identical.

Current single-photon sources using semiconductor quantum dots inserted into photonic structures produce photons that are ultrabright but have limited indistinguishability due to charge noise, which results in a fluctuating electric field. Conversely, parametric down conversion sources yield photons that while being highly indistinguishable have very low brightness. Recently, however, scientists at CNRS – Université Paris-Saclay, Marcoussis, France; Université Paris Diderot, Paris, France; University of Queensland, Brisbane, Australia; and Université Grenoble Alpes, CNRS, Institut Néel, Grenoble, France; have developed devices made of quantum dots in electrically-controlled cavities that provide large numbers of highly indistinguishable photons with strongly reduced charge noise that are 20 times brighter than any source of equal quality. The researchers state that by demonstrating efficient generation of a pure single photon with near-unity indistinguishability, their novel approach promises significant advances in optical quantum technology complexity and scalability. , Physical Review Letters Senellart adds that while removing scattered photons when transmitting light in processed microstructures is typically complicated, in their case this step was straightforward. “Because the quantum dot is inserted in a cavity, the probability of the incident laser light to interact with the quantum dot is actually very high. It turns out that we send only a few photons – that is, less than 10 – on the device to have the quantum dot emitting one photon. This beautiful efficiency, also demonstrated in the excitation process, which we report in another paper5, made this step quite easy.”The devices reported in the paper have a number of implications for future technologies, one being the ability to achieve strongly-reduced charge noise by applying an electrical bias. “Charge noise has been extensively investigated in quantum dot structures,” Senellart says, “especially by Richard Warburton’s group.” Warburton and his team demonstrated that in the best quantum dot samples, the charge noise could take place on a time scale of few microseconds6 – which is actually very good, since the quantum dot emission lifetime is around 1 nanosecond. However, this was no longer the case in etched structures, where a strong charge noise is always measured on very short time scale – less than 1 ns – that prevents the photon from being indistinguishable. “I think the idea we had – that this problem would be solved by applying an electric field – was an important one,” Senellart notes. “The time scale of this charge noise does not only determine the degree of indistinguishability of the photons, it also determines how many indistinguishable photon one can generate with the same device. Therefore, this number will determine the complexity of any quantum computation or simulation scheme one can implement.” Senellart adds that in a follow-up study7 the scientists generated long streams of photons that can contain more than 200 being indistinguishable by more than 88%.In addressing how these de novo devices may lead to new levels of complexity and scalability in optical quantum technologies, Senellart first discusses the historical sources used develop optical quantum technologies. She makes the point that all previous implementations of optical quantum simulation or computing have been implemented using Spontaneous Parametric Down Conversion (SPDC) sources, in which pairs of photons are generated by the nonlinear interaction of a laser on a nonlinear crystal, wherein one photon of the pair is detected to announce the presence of the other photon. This so-called heralded source can present strongly indistinguishable photons, but only at the cost of extremely low brightness. “Indeed, the difficulty here is that the one pulse does not contain a single pair only, but some of the time several pairs,” Senellart explains. “To reduce the probability of having several pairs generated that would degrade the fidelity of a quantum simulation, calculation or the security of a quantum communication, the sources are strongly attenuated, to the point where the probability of having one pair in a pulse is below 1%. Nevertheless, with these sources, the quantum optics community has demonstrated many beautiful proofs of concept of optical quantum technologies, including long-distance teleportation, quantum computing of simple chemical or physical systems, and quantum simulations like BosonSampling.” (A BosonSampling device is a quantum machine expected to perform tasks intractable for a classical computer, yet requiring minimal non-classical resources compared to full-scale quantum computers.) “Yet, the low efficiency of these sources limits the manipulation to low photon numbers: It takes typically hundreds of hours to manipulate three photons, and the measurement time increases exponentially with the number of photons. Obviously, with the possibility to generate more many indistinguishable photons with an efficiency more than one order of magnitude greater than SPDC sources, our devices have the potential to bring optical quantum technologies to a whole new level.”Other potential applications of the newly-demonstrated devices will focus on meeting near-future challenges in optical quantum technologies, including scalability of photonic quantum computers and intermediate quantum computing tasks. “The sources presented here can be used immediately to implement quantum computing and intermediate quantum computing tasks. Actually, very recently – in the first demonstration of the superiority of our new single photon sources – our colleagues in Brisbane made use of such bright indistinguishable quantum dot-based single photon sources to demonstrate a three photon BosonSampling experiment8, where the solid-state multi-photon source was one to two orders-of-magnitude more efficient than downconversion sources, allowing to complete the experiment faster than those performed with SPDC sources. Moreover, this is a first step; we’ll progressively increase the number of manipulated photons, in both quantum simulation and quantum computing tasks.”Another target area is quantum communications transfer rate. “Such bright single photon sources could also drastically change the rate of quantum communication protocols that are currently using attenuated laser sources or SPDC sources. Yet, right now, our sources operate at 930 nm when 1.3 µm or 1.55 µm sources are needed for long distance communications. Our technique can be transferred to the 1.3 µm range, a range at which single photon emission has been successfully demonstrated – in particular by the Toshiba research group – slightly changing the quantum dot material. Reaching the 1.55 µm range will be more challenging using quantum dots, as it appears that the single photon emission is difficult to obtain at this wavelength. Nevertheless, there’s a very promising alternative possibility: the use of a 900 nm bright source, like the one we report here, to perform quantum frequency conversion of the single photons. Such efficient frequency conversion of single photons has recently been demonstrated, for example, in the lab of Prof. Yoshie Yamamoto at Stanford9.”Regarding future research, Senellart says “There are many things to do from this point. On the technology side, we will try to improve our devices by further increasing the source brightness. For that, a new excitation scheme will be implemented to excite the device from the side, as was done by Prof. Valia Voliotis and her colleagues on the Nanostructures and Quantum Systems team at Pierre and Marie Curie University in Paris and Prof. Glenn Solomon’s group at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Applying this technique to our cavities should allow gaining another factor of four on source brightness. In addition, operating at another wavelength would be another important feature for our devices, since as discussed above, this would allow using the source for quantum telecommunication. For example, a shorter wavelength, in the visible/near infrared range, would open new possibilities to interconnect various quantum systems, including ions or atoms through their interaction with photons, as well as applications in quantum imaging and related fields.” The researchers also want to profit from the full potential of these sources and head to high photon number manipulation in, for instance, quantum simulation schemes. “We’re aiming at performing BosonSampling measurements with 20-30 photons, with the objective of testing the extended Church Turing thesis and proving the superiority of a quantum computer over a classical one.” The original Church Turing thesis, based on investigations of Alonzo Church and Alan Turing into computable functions, states that, ignoring resource limitations, a function on the natural numbers is computable by a human being following an algorithm, if and only if it is computable by a Turing machine.Another promising impact on future optical quantum technologies is the generation of entangled photon pairs. “A quantum dot can also generate entangled photon pairs, and in 2010 we demonstrated that we could use the in situ lithography to obtain the brightest source of entangled photon pairs10. That being said, photon indistinguishability needs to be combined with high pair brightness – and this is the next challenge we plan to tackle. Such a device would play an important role in developing quantum relays for long distance communication and quantum computing tasks.”Senellart tells Phys.org that other areas of research might well benefit from their findings, in that devices similar to the one the scientists developed to fabricate single photon sources could also provide nonlinearities at the low photon count scale. This capability could in turn allow the implementation of deterministic quantum gates, a new optical quantum computing paradigm in which reversible quantum logic gates – for example, Toffoli or CNOT (controlled NOT) gates– can simulate irreversible classical logic gates, thereby allowing quantum computers to perform any computation which can be performed by a classical deterministic computer. “Single photons can also be used to probe the mechanical modes of mechanical resonator and develop quantum sensing with macroscopic objects. Other applications,” she concludes, “could benefit from the possibility to have very efficient single photon sources, such as an imaging system with single photon sources that could allow dramatically increased imaging sensitivity. Such technique could have applications in biology where the lower the photon flux, the better for exploring in vivo samples.” “Indeed, for the photons to be fully indistinguishable, the emitter should be highly isolated from any source of decoherence induced by the solid-state environment. However, our study showed that collisions of the carriers with phonons and fluctuation of charges around the quantum dot were the main limitations.” To solve this problem, the scientists added an electrical control to the device3, such that the application of an electric field stabilized the charges around the quantum dot by sweeping out any free charge. This in turn removed the noise. Moreover, she adds, this electrical control allows tuning the quantum dot wavelength – a process that was previously done by increasing temperature at the expense of increasing vibration. “I’d like to underline here that the technology described above is unique worldwide,” Senellart stresses. “Our group is the only one with such full control of all of the quantum dot properties. That is, we control emission wavelength, emission lifetime and coupling to the environment, all in a fully deterministic and scalable way.”Specifically, implementing control of the charge environment for quantum dots in connected pillar cavities, and applying an electric field on a cavity structure optimally coupled to a quantum dot, required significant attention. “We had strong indications back in 2013 that the indistinguishability of our photons was limited by some charge fluctuations around the quantum dot: Even in the highest-quality semiconductors, charges bound to defects fluctuate and create a fluctuating electric field. In the meantime, several colleagues were observing very low charge noise in structures where an electric field was applied to the quantum dot – but this was not combined with a cavity structure.” The challenge, Senellart explains, was to define a metallic contact on a microcavity (which is typically a cylinder with a diameter of 2-3 microns) without covering the pillar’s top surface.”We solved this problem by proposing a new kind of cavity – that is, we showed that we can actually connect the cylinder to a bigger frame using some one-dimensional bridges without modifying too much the confinement of the optical field.” This geometry, which the researchers call connected pillars, allows having the same optical confinement as an isolated pillar while defining the metallic contact far from the pillar itself. Senellart says that the connected pillars geometry was the key to both controlling the quantum wavelength of dot and efficiently collecting its emission3.In demonstrating the efficient generation of a pure single photon with near-unity indistinguishability, Senellart continues, the researchers had one last step – combining high photon extraction efficiency and perfect indistinguishability – which they did by implementing a resonant excitation scheme of the quantum dot. “In 2013, Prof. Chao-Yang Lu’s team in Hefei, China showed that one could obtain photons with 96% indistinguishability by exciting the quantum dot state in a strictly resonant way4. Their result was beautiful, but again, not combined with an efficient extraction of the photons. The experimental challenge here is to suppress the scattered light from the laser and collect only the single photons radiated by the quantum dot.” This document is subject to copyright.
