Atom Computing raises $15M for its quantum system

Atom Computing, a start-up based in Berkeley, California, announced $15 million in Series A funding for its first-generation quantum computing system.

Atom Computing is building nuclear-spin qubits out of an alkaline earth element. The company's first-generation quantum computing system, Phoenix, is currently capable of trapping 100 atoms in a vacuum chamber with optical tweezers. Phoenix is able to rearrange and manipulate their quantum states with lasers. The company said its design demonstrates exceptionally stable qubits at scale, with coherence times that are orders of magnitude greater than ever reported.

Atom Computing also announced the appointment of Rob Hays as CEO, President and member of Atom Computing's Board of Directors. Hays was most recently Vice President and Chief Strategy Officer for Lenovo's Infrastructure Solutions Group. He also served at Intel for more than 20 years, where he was Vice President and General Manager responsible for leading Intel's Xeon processor roadmaps. Company co-founder and CTO, Ben Bloom, Ph.D., will continue leading Atom Computing's engineering team.

"Quantum computing has accelerated to a point where it is no longer 10 years out. The scalability and stability of our systems gives us confidence that we will be able to lead the industry to true quantum advantage," said Rob Hays, CEO and President, Atom Computing.

The FSP 3000 ConnectGuard optical encryption solution relies on a hybrid key exchange system, combining PQC algorithms with classical encryption methods. It utilizes the traditional Diffie-Hellman protocol and combines it with a newly developed algorithm based on the quantum-safe McEliece cryptosystem. This enables it to produce encryption keys that even quantum computers will be unable to crack. As well as delivering data integrity with quantum-safe Layer 1 AES-256 protection, the ADVA FSP 3000 ConnectGuard™ encryption solution ensures minimal impact on latency, throughput and performance.

ADVA said its post-quantum cryptography is deployable over long-haul and multi-operator links.

“Our market-first FSP 3000 quantum-safe ConnectGuard™ encryption technology answers the urgent threat posed by quantum computers and gives organizations a way to safeguard their networks before the danger materializes. Our customers’ data will be fully protected even from cybercriminals’ intent on harvesting information so that they can store it today and exploit it tomorrow,” said Christoph Glingener, CTO, ADVA. “We’re providing long-term security for data in motion. What’s more, our solution is ready to be upgraded later to comply with emerging specifications, including the NIST’s PQC standardization competition.”

“Organizations everywhere have woken up to the security threat that quantum computing represents. With many experts anticipating powerful commercially available quantum computers in the next decade, it’s now widely understood that the danger is very real and the stakes are enormously high. That’s why we’ve invested so much time and energy into developing the world’s first transport solution ready for the challenges ahead,” commented Jörg-Peter Elbers, SVP, advanced technology, ADVA. “By integrating PQC security into our FSP 3000 ConnectGuard™ optical encryption solution, we’re empowering our customers to protect their networks today against tomorrow’s threats. Our solution is easily deployable and only requires end-point access. What’s more, it works over any distance and in any optical transport network.”

NTT develops quantum random number generator

Researchers at NTT have developed a quantum random number generator (QRNG) that exploits the probabilistic nature of quantum measurements to generate genuine random numbers. 

The breakthrough could be implemented as a server that repeatedly produces fixed blocks of fresh, certifiable, public random bits. Applications might include communication networks with high security enhanced by quantum technologies.

NTT said previous high-performance QRNGs require fully characterized quantum devices, which could be subject to security loopholes. Although there are QRNGs that are secure with realistic devices, they need to run for a long time to accumulate sufficient randomness. This results in high latency from the initial request to the delivery of the requested random bits. It is desirable for real-world applications to realize QRNGs of low latency, high rate and high security. In this work, by developing an efficient method for certifying randomness (a collaborative work with the researchers at the National Institute of Standards and Technology) and by measuring the arrival time of an optical pulse with time-bin encoding, NTT was able toshow that every 0.1 seconds a block of 8192 quantum-safe random bits can be generated, enabling low-latency high-rate performance.

NTT Research and Caltech to develop coherent ising machine

NTT Research has signed a collaboration agreement with Caltech to develop a high-speed Coherent Ising Machine (CIM). 

A CIM is a network of optical parametric oscillators (OPOs) programmed to solve problems that have been mapped to an Ising model, which is a mathematical abstraction of magnetic systems composed of competitively interacting spins, or angular momentums of fundamental particles. The CIM is particularly suited to combinatorial optimization problems that are beyond the capabilities of current computer processors to solve. NTT Research and Caltech will jointly develop a high-speed, miniature CIM, consisting of an on-chip 100 GHz pulsed pump laser source and on-chip parametric oscillator device.

The principal investigator at Caltech for this four-and-a-half-year joint project is Kerry Vahala, the Jenkins Professor of Information Science and Technology and Applied Physics and Executive Officer for the department of Applied Physics and Materials Science. Professor Vahala has pioneered the use of nonlinear optics in high-Q optical micro-resonators. Leading this effort at NTT Research is PHI Lab Research Scientist, Dr. Myoung-Gyun Suh, an expert in on-chip optical sources and their application to precision measurements.

“We are delighted at the prospect of working with Professor Vahala to develop an extremely small and high-speed CIM,” said NTT Research PHI Lab Director, Yoshihisa Yamamoto. “This work will advance our understanding of the CIM’s capabilities, map well with ongoing and related work with other institutions, provide new demonstrations of this awesomely powerful new information system and, we hope, set standards for the CIM’s speed and size.”

To date, the NTT Research PHI Lab has established ten joint research projects as part of its long-range goal to radically redesign artificial computers, both classical and quantum. To advance that goal, the PHI Lab has established joint research agreements with seven universities, one government agency and quantum computing software company. This is the second joint research agreement with Caltech. The other institutions of higher education are Cornell University, Massachusetts Institute of Technology (MIT), Stanford University, Swinburne University of Technology, the University of Michigan and the University of Notre Dame. 

NTT Tackles Artificial Spin for Photonic Computation

Researchers at NTT and and Osaka University announced an important step toward photonic computation by developing a large-scale artificial spin network based on photonics technologies.

NTT researchers streamline quantum calculations with ZX-Calculus

Researchers at NTT are pursuing a novel method to reduce the resources associated with large-scale fault-tolerant quantum circuits by employing ZX-calculus.

Currently, a fault-tolerant quantum circuit for a given computation requires a huge amount of resources, both in terms of qubits and computational time. The researchers at NTT have found an efficient method to compress such circuits with the purpose of decreasing their hardware demands. They use ZX-Calculus as an intermediate language to reduce both the number of qubits and time required to perform such computation in many different circuits. 

A paper on the topic discusses an improvement of a 40% compression rate with respect to previous reductions, yielding compression rates higher than 70% compared to the initial circuit. The methodology proposed in this work promises to open new venues of research in large-scale quantum computing and bring quantum computation closer to reality by relaxing its hardware demands.

Verizon tests Quantum Key Distribution

Verizon set-up a trial Quantum Key Distribution (QKD) network in the Washington D.C. area.

Live video was captured outside of three Verizon locations in the D.C. area, including the Washington DC Executive Briefing Center, the 5G Lab in D.C and Verizon’s Ashburn, VA office. Using a QKD network, quantum keys were created and exchanged over a fiber network between Verizon locations. Video streams were encrypted and delivered more securely allowing the recipient to see the video in real-time while ensuring hackers are instantly detected.

A QKD network derives cryptographic keys using the quantum properties of photons to prevent against eavesdropping. Verizon also demonstrated that data can be further secured with keys generated using a Quantum Random Number Generator (QRNG) that creates truly random numbers that can’t be predicted. With QKD, encryption keys are continuously generated and are immune to attacks because any disruption to the channel breaks the quantum state of photons signaling
eavesdroppers are present.

"The use of quantum mechanics is a great step forward in data security,” said Christina Richmond, analyst at IDC. “Verizon's own tests, as well other industry testing, have shown that deriving "secret keys" between two entities via light photons effectively blocks perfect cloning by an eavesdropper if a key intercept is attempted. Current technological breakthroughs have proven that both the quantum channel and encrypted data channel can be sent over a single optical fiber. Verizon has demonstrated this streamlined approach brings greater efficiency for practical large-scale implementation allowing keys to be securely shared over wide-ranging networks.”

MIT advances quantum information sharing between processors

Researchers at MIT are developing an on-off system that leverages "giant atoms" to enable high-fidelity operations and interconnection between processors.

A key challenge in quantum computing has been to communicate quantum information between distant parts of a processor.

In a paper published in the journal Nature, the MIT researchers constructed “giant artificial atoms” from superconducting quantum bits, or qubits, connected in a tunable configuration to a microwave transmission line, or waveguide.

“Coupling a qubit to a waveguide is usually quite bad for qubit operations, since doing so can significantly reduce the lifetime of the qubit,” says Bharath Kannan, MIT graduate fellow and first author of the paper. “However, the waveguide is necessary in order to release and route quantum information throughout the processor. Here, we’ve shown that it’s possible to preserve the coherence of the qubit even though it’s strongly coupled to a waveguide. We then have the ability to determine when we want to release the information stored in the qubit. We have shown how giant atoms can be used to turn the interaction with the waveguide on and off.”

“We are delighted to be participating in these exciting endeavors with the University of Glasgow,” said SPIE President John Greivenkamp. “The interactive placements will offer transformative opportunities the university’s academic and industry-based researchers, and, together with the annual scholarship, will develop well-prepared, knowledgeable early-career researchers who will drive the future of the quantum industry.”

“We’re pleased and proud to be establishing the Early Career Researcher Accelerator Fund in Quantum Photonics thanks to SPIE’s generous gift, which we’re very happy to match with our own funding,” said Professor Sir Anton Muscatelli, principal and vice-chancellor of the University of Glasgow:. “The University’s quantum photonics expertise is world-leading, and our researchers have found ways to see through walls, capture images at a trillion frames per second, and take the very first pictures of quantum entanglement in action. This additional funding will help the University train a new generation of graduate students to make valuable contributions to academia and industry and inspire them to make their own amazing research breakthroughs.”

Blueprint for the Quantum Internet

The U.S. Department of Energy (DOE) outlined a blueprint strategy for the development of a national Quantum Internet.

The DoE's 17 national laboratories will serve as the first nodes on the Quantum Internet. Also participating will be the National Science Foundation, the Department of Defense, the National Institute for Standards and Technology, the National Security Agency, and NASA. The academic community and industry will also be invited.

At a launch event hosted by the University of Chicago, officals described the initiative as "bringing the United States to the forefront of the global quantum race and ushering in a new era of communications."

“The Department of Energy is proud to play an instrumental role in the development of the national quantum internet,” said U.S. Secretary of Energy Dan Brouillette. “By constructing this new and emerging technology, the United States continues with its commitment to maintain and expand our quantum capabilities.”

In February, scientists from DOE’s Argonne National Laboratory in Lemont, Illinois, and the University of Chicago entangled photons across a 52-mile “quantum loop” in the Chicago suburbs, successfully establishing one of the longest land-based quantum networks in the nation. That network will soon be connected to DOE’s Fermilab in Batavia, Illinois, establishing a three-node, 80-mile testbed.

“The combined intellectual and technological leadership of the University of Chicago, Argonne, and Fermilab has given Chicago a central role in the global competition to develop quantum information technologies,” said Robert J. Zimmer, president of the University of Chicago. “This work entails defining and building entirely new fields of study, and with them, new frontiers for technological applications that can improve the quality of life for many around the world and support the long-term competitiveness of our city, state, and nation.”

 “Argonne, Fermilab, and the University of Chicago have a long history of working together to accelerate technology that drives U.S. prosperity and security,” said Argonne Director Paul Kearns. “We continue that tradition by tackling the challenges of establishing a national quantum internet, expanding our collaboration to tap into the vast power of American scientists and engineers around the country.”
