Physics – Tweezers in Three Dimensions – Physics

May 5, 2023• Physics 16, 75

A new kind of 3D optical lattice traps atoms using focused laser spots replicated in multiple planes and could eventually serve as a quantum computing platform.

Researchers have produced 3D lattices of trapped atoms for possible quantum computing tasks, but the standard technology doesnt allow much control over atom spacing. Now a team has created a new type of 3D lattice by combining optical tweezerspoints of focused light that trap atomswith an optical phenomenon known as the Talbot effect [1]. The teams 3D tweezer lattice has sites for 10,000 atoms, but with some straightforward modifications, the system could reach 100,000 atoms. Such a large atom arrangement could eventually serve as a platform for a quantum computer with error correction.

3D optical lattices have been around for decades. The standard method for creating them involves crossing six laser beams to generate a 3D interference pattern that traps atoms in either the high- or low-intensity spots (see Synopsis: Pinpointing Qubits in a 3D Lattice). These cold-atom systems have been used as precision clocks and as models of condensed-matter systems. However, the spacing between atoms is fixed by the wavelength of the light, which can limit the control researchers have over the atomic behavior.

Optical tweezers offer an alternative method for trapping and controlling atoms. To form a tweezer array, researchers pass a single laser beam through a microlens array (or similar device) that focuses the beam into a 2D pattern of multiple bright spots. Atoms are automatically drawn to the centers of these spots, forming an array in a single plane (see Viewpoint: Alkaline Atoms Held with Optical Tweezers). We take these tweezer arrays to the third dimension, says Malte Schlosser from the Technical University of Darmstadt, Germany.

To obtain a 3D lattice, Schlosser and his colleagues took advantage of the Talbot effect, which is an interference phenomenon that occurs when light strikes a periodic structure, such as a diffraction grating or a microlens array. The light exiting the structure produces a 2D interference pattern of bright spots at some fixed distance beyond the structure but also generates additional planes of spots parallel to the first one. The Talbot effect had long been considered a nuisance for tweezer array research, as it creates extra bright spots that trap stray atoms, which interferes with measurements. The researchers turned this bug into a feature by deliberately tuning their optical system to trap atoms in the extra bright spots, Schlosser explains.

The researchers shined an 800-milliwatt laser onto a microlens array, which produced a 2D square array of 777 atom traps at the focal plane of the lens. But thanks to the Talbot effect, this 2D array was reproduced in 17 parallel planes, giving a total of 10,000 atom traps. These Talbot planes come for free, so we dont have to put in additional laser power or additional laser beams, Schlosser says.

As a demonstration of their system, Schlosser and his colleagues showed that they could load around 50% of the traps with rubidium atoms and induce an optical transition in all the atoms in a sublattice. In the future, the team plans to use a focused laser beam to selectively excite a single atom. Such optical control could allow researchers to read the atoms state or to place it in a so-called Rydberg state that would let it interact with its neighbors. Control of atomatom interactions has been previously demonstrated in 2D tweezer arrays. Schlosser foresees having atomatom interactions in the 3D lattice, but currently the spacing between the planes is too large (around 100 m); a distance of 10 m or less would be required.

Besides squeezing down the spacing of the lattice, the team plans to explore other trap geometries, such as hexagonal patterns that could mimic materials like graphene. The researchers are also working to boost the laser power. More light will increase the number of traps in the lattice. They estimate that doubling the power would provide 30,000 traps and that quadrupling it should produce close to 100,000.

Schlosser and his colleagues are tackling one of the most important challenges any quantum computing technology will face, which is scaling, says Ben Bloom, founder and chief technology officer of Atom Computing, a quantum technology company in California. He says that the new design can create a large number of atom quantum bits at essentially no cost, but there will be challenges ahead in trying to control the atoms within the lattice. Still, controlling so many atoms will have practical benefits. Pushing to large numbers of individually controlled atoms in 3D will allow for the exploration of new quantum error-correction codes, Bloom says.

Omdia forecasts quantum computing market will grow more than 22x … – PR Newswire

LONDON, May 2, 2023 /PRNewswire/ -- Omdia forecasts that quantum computing vendors will see their global revenue rise from $942 million in 2022 to $22 billion in 2032, for a compound annual growth rate of 57.7% over this ten-year period. North America and Europe are expected to be the leading regional markets, with Asia & Oceania a close third. Cloud-based access services will make up the largest share of revenue, followed by hardware, consulting, and software. Omdia also believes 2027 will be a key inflection point in the market, and that the chances of a "quantum winter" are very small (less than 1%).

Near term, Omdia believes examples of "quantum commercial advantage" in which a quantum computer supplies a measurable advantage in speed, cost, quality, or efficiency over the typical classical alternative for a problem of commercial interest will grow steadily. By 2027, enough of these examples will be clear across enough verticals and industries that adopters will shift from "experimenting with quantum computing" to "deploying quantum computing for operational needs."

"Achieving fault-tolerant scaled quantum computing would help humanity solve key challenges related to climate change, developing new pharmaceuticals and materials, and bringing important advances to artificial intelligence." says Sam Lucero, Chief Analyst for Quantum Computing at Omdia. "But the industry has a long road to fully achieving this goal."

Recently, concerns have grown about the possibility of a "quantum winter". However, Omdia notes several factors protecting against such a downturn, including growing investments in vendors, strong government support, diverse technology options, and steady technology advancements by vendors.

"While a 'quantum winter' is possible," says Lucero "the chance of it happening is far outweighed by the likelihood of continued steady progress towards fault-tolerant, scaled quantum computers."

Omdia published its annual quantum computing market forecast report in April 2023.

Look who won in the NYUAD hackathon for quantum computing solutions? – Gulf News

Abu Dhabi: A solution that minimises power blackouts has won the top prize at an international quantum computing hackathon hosted by the NYU Abu Dhabi. The winning idea from the NYUAD Hackathon for Social Good in the Arab World will be presented at a high-level international platform in Geneva in October, following an agreement signed by the university with science and diplomacy organisation, the Geneva Science and Diplomacy Anticipatory Foundation (GESDA).

The 11th edition of the three-day programming marathon was organised by NYUAD in partnership with social initiative company Tamkeen. The initiative encourages participants to find innovative solutions through quantum computing for challenges related to the UN Sustainable Development Goals.

This year, the event concluded with the signing of the NYUAD Memorandum of Understanding with GESDA. In the presence of Caroline Trautweiler, deputy ambassador of Switzerland to the UAE and Bahrain, the two entities agreed to collaborate towards advancing the role that quantum computing can play in solving the worlds most pressing issues and sustainability challenges, and towards highlighting the importance of quantum computing education for all. As part of its long-term strategic partnership with NYUAD GESDA will grant an Open Quantum Institute prize to the top winners, which offers access to mentorship, industry networking opportunities, academic research, and an open invitation to attend the Geneva Science and Diplomacy Anticipation Summit in October 2023. Additionally, GESDA announced it will invite the first-place winners, a team named Smart Current, to present their project at the GESDA Summit in October in Geneva to diplomats, UN leaders, scientists and more.

This year, more than 200 students participated in the contest. Apart from winning team Smart Current, QatraH devised quantum solutions to ensure a robust water distribution network, and won the second prize. feeQra, the team that placed third, showed how quantum computing can be used to detect early signs of malignant tumours.

Smart Current, QatraH, and feeQra were the top three winners of this years Hackathon, respectively. They were among the more than 200 elite students from 24 countries who gathered to develop quantum computing-based applications that further the objectives of the UN SDGs.

We founded the NYUAD International Hackathon for Social Good 11 years ago on our firm belief that technology can aid society. Quantum computing has the potential to transform many fields, but the biggest area where it could help is in solving our greatest challenge: Climate change and the need for a more sustainable future. The aim of the hackathon was to direct this powerful technology specifically toward the UN Sustainable Development Goals (SDGs). This gave our participating students, who came from all around the world, a real focus for their talents and energy, and I am once again humbled by the results, said Sana Odeh, NYUAD affiliated faculty, and clinical professor of Computer Science. Odeh organised the hackathon this year.

This new generation of global talent has used the Hackathon platform to give birth to ideas that can truly have a transformative impact on the future of our society. I thank everyone who participated, along with the mentors and judges who provided valuable counsel, and our partners and sponsors who have all helped make this event a great success, she added.

Experts from world-leading institutions, including ETH, MIT, and Stanford, acted as a source of sponsorship and mentorship to the students, sharing their experiences and insights into the world of tech startups and academic research.

Software engineers get the ball rolling as they wait for quantum computers to arrive, a number of public Salesforce sites leak private data and the first wooden transistor is here.

These top tech news stories and more for Wednesday, May 3rd, 2023. Im your guest host, James Roy.

Weve heard a lot of endless superpowers of quantum computers, be it to revolutionize medical research or solve climate change. Millions are being poured into these machines, hailed as being a million times faster than todays fastest computers. But they are yet to hit the market.

However, quantum startups are getting creative despite lacking these powerful computers.

QC Ware, a software startup initially focused only on software that could run on quantum computers.

But the company now said it needed to change tack to find a solution until the future quantum machines arrive.

Investors are not shying away either, despite the dismal stock performance of publicly-listed quantum computer companies. QC Ware, in fact, raised more than $33 million.

What these startups are doing is nothing short of brilliant;

They are developing a new breed of software inspired by algorithms used in quantum physics which is a branch of science that studies the fundamental building blocks of nature.

These algorithms, once too big for conventional computers, are being put to work thanks to todays powerful artificial intelligence chips.

QC Ware CEO, Matt Johnson said it turned to Nvidias GPUs to figure out how can we get them something that is a big step change in performance and build a bridge to quantum processing in the future.

This week, QC Ware is unveiling a quantum-inspired software platform called Promethium that will simulate chemical molecules to see how they interact with things like protein on a traditional computer using GPUs.

The companys head of quantum chemistry said the software can cut simulation time from hours to minutes for molecules of 100 atoms, and months to hours for molecules of up to 2000 atoms, compared with existing software solutions.

According to a report by KrebsOnSecurity, a number of organizations, including banks, healthcare and government agencies are leaking private and sensitive information through their public Salesforce Community websites.

Reportedly, the leaking stems from a misconfiguration in Salesforce Community that allows an unauthenticated user to access records that should only be available after logging in.

Salesforce Community is a widely-used cloud-based software that makes it easy for organizations to create websites.

Customers can access a Salesforce Community website by either logging in or through guest user access, which allows unauthenticated users to view specific content and resources, without logging in.

But sometimes Salesforce administrators also mistakenly grant users access to internal resources which can cause unauthorized access and data leaks.

The state of Vermont, for instance, allowed guest access to sensitive data to at least five separate Salesforce Community websites, including one for a Pandemic Unemployment Assistance program that exposed applicants full name, SIN number, phone number, bank account number and more.

Vermonts Chief Information Security Officer Scott Carbee said, During the pandemic, we were largely standing up tons of applications, and lets just say a lot of them didnt have the full benefit of our dev/ops process. In our case, we didnt have any native Salesforce developers when we had to suddenly stand up all these sites.

But, Carbee also denounced the permissive nature of the platform

On Monday, KrebsOnSecurity notified Washington D.C. city administrators that at least five different public DC Health websites were leaking sensitive information.

Interim CISO, Mike Rupert said the District had hired a third party to investigate and it revealed that the Districts IT systems were not vulnerable to data loss.

But after being presented with a document including the Social Security number of a health professional in D.C. that was downloaded in real-time from the DC Health public Salesforce website, Rupert acknowledged his team had overlooked some configuration settings.

Meanwhile, Salesforce maintains that the data exposures are not the result of a vulnerability inherent to Salesforce but occur when customers access control permissions are misconfigured.

In a written statement, Salesforce said it is actively focused on data security for organizations with guest users, and that it continues to release robust tools and guidance for our customers.

The Federal Trade Commission (FTC) has a new proposed rule to fight the absolute headache that canceling subscriptions can be.

The proposed provision, Click-to-Cancel, seeks to make it as easy to cancel enrollment as it was to sign up.

FTC Chair Lina M. Khan said, Some businesses too often trick consumers into paying for subscriptions they no longer want or didnt sign up for in the first place.The proposal would save consumers time and money, and businesses that continued to use subscription tricks and traps would be subject to stiff penalties.

The new proposal will mandate a simple cancellation mechanism. For instance, if you signed up online, you must be able to cancel on the same website in the same number of steps.

Secondly, the proposal would require sellers to ask customers whether they want to be pitched other offers upon cancellation. Sellers must take no for an answer if thats the case and immediately expedite the cancellation process.

Finally, and that, no doubt would be helpful to many of us, the proposed rule would require sellers to provide an annual reminder to consumers enrolled in subscriptions, before they are automatically renewed.

Akash Nigam, CEO of avatar technology company Genies revealed to Insider that he is spending $2,400 a month on ChatGPT accounts for all 120 of his employees as part of an experiment to boost productivity.

Nigam says he is already seeing stuff getting done faster.

He said that Genies R&D team, for instance, has used ChatGPT to answer math and coding questions, get advice on how to debug code, and generate scripts for presentations based on outlines. Other employees have used it to generate creative briefs, write legal documents and answer technical questions.

Not everyone is using ChatGPT but he is encouraging everyone to make learning the technology a priority.

Employees who are more productive as a result of using ChatGPT will be up for a raise or a promotion. Others, he says, will fall behind

He also believes that the use of the technology can help his company reduce costs as he will need to hire less employees.

Genies is not the only company diving head first with ChatGPT. Amazon, Microsoft and design firm Pure Fusion Media have also strongly encouraged employees to use AI.

The link between increased cyberthreats and AI however, remains unclear. Some say it might be overblown.

John Dwyer, head of research at IBM Security X-Force, told Axios, Cybercriminals are often looking for the simplest, quickest schemes to make money, and bringing todays AI into play doesnt fit that bill.

If anything, its cyber defenders who will exploit AI to counter the run-of-the-mill security holes that criminals keep exploiting.

Palo Alto Networks and Mandiant are the big names already playing around ChatGPT and other AI tools to improve their security products.

Michael Sikorski, CTO of Palo Alto Networks threat intelligence team revealed that most of the malicious code spewed by AI tools are repurposed from previous attacks. He adds, maybe they are faster, but they are not new. And its definitely not trained on how to write a zero-day or find or exploit a vulnerability.

Plus, according to Chester Wisniewski, field CTO of applied research at Sophos, most hackers do not double up as data scientists or are not training the AI models themselves. Theyll need to bring make enough money from the malicious AI for it to be worth it.

But, Wisniewski says, the upside is the good guys do have data scientists, and many of us do spend millions of dollars in the cloud on GPUs

However, we still need to be wary. Many cybercriminals are using simple AI tools to get people to respond to phishing emails and scam texts.

And many companies continue to suffer from attacks with already publicly known flaws that companies failed to patch.

Rob Joyce, director of cybersecurity at the National Security Agency, said during the RSA Conference, Ill tell you, buckle up. Next year, if were talking a similar year in review, well have a bunch of examples of where its been used and where its succeeded.

Swedish researchers have built what they claim is the worlds first wooden transistors.

Its shaped like a T and made from three pieces of balsa wood.

The top of the T served as the transistor channel, with a source at one end and a drain at the other, while the vertical portion of the T used two pieces of balsa with a gap between them to form the transistors gate pieces.

Before you start gathering your tools and your balsa wood, remember that in order to make the wood conductive, the researchers had to expose it to heat and use chemicals to replace the lignin with conductive polymer.

Once filled with the polymer and assembled, the Swedish team achieved conductivity up to 69 Sm-1, and were also able to prove the devices effectiveness as a double-gate organic electrochemical transistor and functional on/off switch.

Previous wooden transistors could only regulate ions transport and would stop functioning once the ion ran out. This one does not work like that and still functions without deteriorating.

But, unfortunately this breakthrough is not going to revolutionize the semiconductor industry. The balsa wood transistor is neither small nor fast. Its so slow its unable to switch off under a second and switching on takes a full five seconds. Not exactly super computing speeds.

But for the researchers, this proves that it is possible to modulate the electrical conductivity of the electroactive wood by applying an external voltage.
