New research published in Physical review letter Describes how electrons move through two different configurations of two-layer graphene, which is an atomically thin form of carbon.This study was conducted at Brookhaven National Laboratory, University of Pennsylvania, New Hampshire University, Stony Brook University, and Columbia UniversityProvides insights that researchers can use to design more powerful and secure quantum computing platforms in the future.

Todays computer chips are based on knowledge of how electrons move in semiconductors, especially silicon, said Zhongwei Dai, the first co-author of a Brookhaven postdoc. But the physical properties of silicon are reaching their physical limits in how small transistors can be made and how many can fit on a chip. Quantum is shrinking in two-dimensional materials. Understanding how it works on a small scale of a few nanometers in another dimension could unleash another way to use electrons in quantum information science.

When a material is designed to a size of a few nanometers on these small scales, the electrons are confined in a space of the same dimensions as its own wavelength, and the overall electronic and optical properties of the material are a process that follows: It changes with. Quantum confinement. In this study, researchers used graphene to study these confinement effects on both electrons and photons, or particles of light.

This work relied on two independently developed advances in Penn and Brookhaven. Pen researchers, including former postdoctoral fellow Zhaoli Gao in Charlie Johnsons lab, currently enrolled at the Chinese University of Hong Kong, used their own gradients-alloy A growth substrate for growing graphene with three different domain structures: single layer, Bernal stack double layer, and twisted double layer. Next, the graphene material was transferred to a special substrate developed in Brookhaven. This allowed researchers to investigate both the electronic and optical resonances of the system.

This is a great collaboration, says Johnson. By combining the great features of Brookhaven and the pen, we can make important measurements and discoveries that none of us can do on our own.

Researchers have been able to detect both electronic and optical interlayer resonances, and have found that in these resonance states, electrons move back and forth across the 2D interface at the same frequency. Their results also suggest that the distance between the two layers increases significantly in a twisted configuration, which affects how electrons move due to interlayer interactions. They also found that twisting one of the graphene layers by 30 shifts the resonance to lower energies.

Devices made of rotated graphene can have very interesting and unexpected properties due to the large spacing between electrons that can move, said Julek Sadowski, co-author of Brookhaven. increase.

In the future, researchers will use twisted graphene to build new devices, and at the same time, based on the results of this study, adding various materials to the layered graphene structure will result in downstream electronic and optical properties. See how it affects you.

We look forward to continuing to work with our Brookhaven colleagues at the forefront of the application of 2D materials in quantum science, says Johnson.

The University of Maryland and IonQ, a College Park-based quantum computing company, announced Wednesday that they will join forces to develop a facility that will give students, faculty, staff and researchers access to a commercial-grade quantum computer.

The new facility, which will be known as the National Quantum Lab at Maryland or Q-Lab for short is the product of a nearly $20 million investment from this university. As the nations first facility of its kind, it will also provide training related to IonQs hardware and allow visitors to collaborate with the companys scientists and engineers, according to a news release.

No other university in the United States is able to provide students and researchers this level of hands-on contact with commercial-grade quantum computing technology and insights from experts working in this emerging field, university President Darryll Pines said in the news release.

The Q-Lab will be located in the Discovery District next to IonQs headquarters by the College Park Airport, the news release stated.

Quantum computing attempts to evolve computer technology, striving to create a machine that can solve more problems at a faster rate.

[Whats new, whats coming, whats moving: The business scene in College Park]

Around the time IonQ announced its plans to go public earlier this year, Pines explained that classical computing uses a stream of electrical pulses called bits, which represent 1s and 0s, to store information. However, on the quantum scale, subatomic particles known as qubits are used to store information, greatly increasing computing speed.

Most importantly, we wanted to put our scientists at the cutting edge of quantum computers because we know that we already use supercomputers, Pines said Wednesday. But why not use the best computers that are right in our backyard?

Recent advancements in quantum computing also support research in areas such as biology, medicine, climate science and materials development, the release noted, adding that the creation of the Q-Lab may also attract additional entrepreneurs and startups to College Park.

We could not be more proud of IonQs success and we are excited to establish this strategic partnership, further solidifying UMD and the surrounding region as the Quantum Capital of the world, Pines added.

The development of the Q-Lab builds upon the universitys $300 million investment in quantum science and more than 30-year history of advancements in the field, according to the news release. The university also currently houses more than 200 researchers and seven centers specializing in quantum-related work.

We are very proud that the nations leading center of academic excellence in quantum research chose IonQs hardware for this trailblazing partnership, said Peter Chapman, the president and CEO of IonQ.

Chris Monroe, a professor in this universitys physics department, and Jungsang Kim co-founded IonQ, which is set to become the first publicly traded commercialized quantum computing company. The company is estimated to go public with a valuation of nearly $2 billion.

The company recently became the first quantum computer supplier whose products are available on all major cloud services providers such as Google Cloud, Microsoft Azure and Amazon Web Services, according to the release.

Monroe and Kim also joined the White Houses National Quantum Initiative Advisory Committee in an effort to accelerate the development of the national strategic technological imperative, the news release stated.

UMD has been at the vanguard of this field since quantum computing was in its infancy, and has been a true partner to IonQ as we step out of the lab and into commerce, industry, and the public markets, Chapman said in the news release.

Senior staff writer Clara Niel contributed to this report.

In July, the European Organisation for Nuclear Research (Cern) announced it would deploy quantum computers (QCs) to power its search for fundamental particles. Unlike a decade ago, QCs are no more tentative prototypes, but fast emerging as a viable tool for niche practical applications ranging from designing novel materials to enabling drug discovery.

QCs are now available as a cloud-based service to anyone with an internet connection. We will see the unveiling of more powerful QCs over the next five years. How prepared is India to ride the quantum technology wave?

Introduced as an idea by Nobel-winning physicist Richard Feynman in the early 1980s, QCs are not merely faster versions of the computers we use but are machines based on the laws of quantum physics. A typical QC hardware computes by manipulating electrons and nuclei using electromagnetic radiation from lasers. The technology is complex as precise control over these delicate manipulation schemes is necessary to perform calculations. If this technology can be mastered, QCs promise, at least for a certain class of problems, unprecedented computational speeds not attainable even by the fastest supercomputers available today.

Barring a few premier institutions, quantum computing is not yet part of the curriculum in most Indian universities and colleges. This issue must be addressed through a programme to skill faculty, enabling them to teach engineering and science undergraduates. By 2024, Indias software developer community is expected to be the largest in the world. By training this community, India can create a quantum workforce for itself and the world.

GoI and the industry must support interdisciplinary research and development in quantum science and technologies. As part of the National Mission on Quantum Technologies and Applications (NM-QTA), the 2020 budget had committed 8,000 crore. Also, a Technology Innovation Hub (TIH) for quantum technologies has been set up at Indian Institute of Science Education and Research (IISER), Pune, focused on translating research into products and services. These investments must increase. At present, private investments are lacking. Industry and PSUs must be incentivised to evaluate and work on applications relevant to their domain.

Quantum technologies include a whole gamut of interrelated technologies quantum cryptography, quantum sensors, quantum materials, quantum meteorology, etc. Products based on quantum cryptography for secure communications are already available in the market. However, unambiguous evidence of societal benefits of QCs is still lacking. Demonstrating a few showcase applications is critical to persuade industry to invest in quantum technologies. These applications could be in drug discovery, logistics and optimisation, new materials, fintech, machine learning and defence. This will have a cascading effect of seeding a vibrant quantum startup ecosystem leading to job-creation and economic growth.

India must build its own competitively sized QC in mission mode by pooling its existing academic expertise. A few indigenous QCs will give India a voice in shaping the future of quantum computing. With the right policy framework and incentives, India has the potential to become a key player in a global quantum technology market anticipated to reach $31.57 billion (2.32 lakh crore) by 2026. This will generate more technical jobs in the coming decades. India must move fast to respond to the fast-evolving quantum landscape.

One of the challenges of writing about technology is how to escape from what the sociologist Michael Mann memorably called the sociology of the last five minutes. This is especially difficult when covering the digital tech industry because one is continually deluged with new stuff viral memes, shiny new products or services, Facebook scandals (a weekly staple), security breaches etc. Recent weeks, for example, have brought the industrys enthusiasm for the idea of a metaverse (neatly dissected here by Alex Hern), El Salvadors flirtation with bitcoin, endless stories about central banks and governments beginning to worry about regulating cryptocurrencies, Apples possible rethink of its plans to scan phones and iCloud accounts for child abuse images, umpteen ransomware attacks, antitrust suits against app stores, the Theranos trial and so on, apparently ad infinitum.

So how to break out of the fruitless syndrome identified by Prof Mann? One way is to borrow an idea from Ben Thompson, a veteran tech commentator who doesnt suffer from it, and whose (paid) newsletter should be a mandatory daily email for any serious observer of the tech industry. Way back in 2014, he suggested that we think of the industry in terms of epochs important periods or eras in the history of a field. At that point he saw three epochs in the evolution of our networked world, each defined in terms of its core technology and its killer app.

Epoch one in this framework was the PC era, opened in August 1981 when IBM launched its personal computer. The core technology was the machines open architecture and the MS-DOS (later Windows) operating system. And the killer app was the spreadsheet (which, ironically, had actually been pioneered as VisiCalc on the Apple II).

Epoch two was the internet era, which began 14 years after the PC epoch began, with the Netscape IPO in August 1995. The core technology (the operating system, if you like) was the web browser the tool that turned the internet into something that non-geeks could understand and use and the epoch was initially characterised by a vicious struggle to control the browser, a battle in which Microsoft destroyed Netscape and captured 90% of the market but eventually wound up facing an antitrust suit that nearly led to its breakup. In this epoch, search was the killer app and, in the end, the dominant use came to be social networking with the dominant market share being captured by Facebook.

Epoch three in Thompsons framework the era were in now was the mobile one. It dates from January 2007 when Apple announced the iPhone and launched the smartphone revolution. Unlike the two earlier eras, theres no single dominant operating system: instead theres a duopoly between Apples iOS and Googles Android system. The killer app is the so-called sharing economy (which of course is nothing of the kind), and messaging of various kinds has become the dominant communications medium. And now it looks as though this smartphone epoch is reaching its peak.

If that is indeed whats happening, the obvious question is: what comes next? What will the fourth epoch be like? And here its worth borrowing an idea from another perceptive observer of these things, the novelist William Gibson, who observed that the future is already here; its just not evenly distributed. If thats as profound as I think it is, then what we should be looking out for are things that keep bubbling up in disjointed and apparently unconnected ways, like hot lava spurts in Iceland or other geologically unstable regions.

So what can we see bubbling up in techland at the moment? If you believe the industry, metaverses (plural) basically conceived as massive virtual-reality environments might be a big thing. That looks to this observer like wishful thinking for psychotics. At any rate, at its extreme end, the metaverse idea is a vision of an immersive, video-game-like environment to keep wealthy humans amused in their air-conditioned caves while the planet cooks and less fortunate humans have trouble breathing. In that sense, the metaverse might just be a way of avoiding unpleasant realities. (But then, as a prominent Silicon Valley figure recently joked, maybe reality is overrated anyway.)

Two more plausible candidates for what will power future epochs are cryptography in the sense of blockchain technology and quantum computing. But an era in which these are dominant technologies would embody an intriguing contradiction: our current crypto tools depend on creating keys that would take conventional computers millions of years to crack. Quantum computers, though, would crack them in nanoseconds. In which case we might finally have to concede that, as a species, were too smart for our own good.
