Since 1987 - Covering the Fastest Computers in the World and the People Who Run Them

It’s been a busy week in quantum computing. Rigetti began providing much wider access to its 80-qubit system (Aspen-M), announced a collaboration with Nasdaq to develop FS apps, and struck a deal with Arm-based chip supplier Ampere to develop hybrid classical-quantum platforms.

Elsewhere, JPMorgan Chase, Toshiba, and Ciena reported successfully demonstrating a “first-of-its-kind” Quantum Key Distribution network for metropolitan areas that resists quantum computing attacks and supports 800Gbps data rates; UColorado’s CUbit Quantum Initiative added commercial members; Classiq took in $33M more in funding; and Israel’s Defense Ministry announced plans to develop a quantum computer.

Let’s start with Rigetti’s announcements.

Last June, the Berkeley-based company introduced its multi-chip design for quantum processors (QPUs); in December, it introduced Aspen-M, the first of those designs, an 80-qubit multi-chip quantum processor. Scaling up QPU size is an ongoing challenge throughout the quantum community, with several companies exploring multi-chip approaches. Rigetti is perhaps furthest along in those efforts, and has said the multi-chip approach is critical to building quantum computers large enough (by number of qubits) to tackle practical problems.

After initially allowing only limited access to Aspen-M, Rigetti has now expanded access to the new chip.

The company reported that “Aspen-M is now available on Rigetti Quantum Cloud Services and will support a number of Rigetti collaborations taking place with both enterprise and public sector customers including Nasdaq, Deloitte, DARPA and the U.S. Department of Energy. Beginning today, Aspen-M will also be available to end users on Amazon Braket, marking the latest in a series of increasingly powerful Rigetti systems offered through the service since Amazon Braket’s launch in 2019. In addition, Rigetti expects the 80-qubit system to be available through Azure Quantum, Strangeworks QC and Zapata’s Orquestra platform in the coming months.”

Of note, Rigetti chose to use an IBM-developed metric – CLOPS, or circuit layer operations per second – to characterize both its recent single-chip Aspen-11 (40 qubits) and its multi-chip Aspen-M (80 qubits) processors. Here’s an excerpt from the announcement:

“Conducting tests based on 100 shots, as set forth in the original published definition, the 40-qubit Aspen-11 system demonstrated a CLOPS of 844, while the 80-qubit Aspen-M system demonstrated a CLOPS of 892. These results suggest that current Rigetti systems perform as well or better on this CLOPS speed test as the number of qubits in the system increases. By comparison, IBM’s published CLOPS scores for systems with 5, 27, and 65 qubits were 1419, 951, and 753, respectively, as of the October 2021 publishing date.

“To reflect what users can potentially expect in typical use cases, Rigetti also evaluated CLOPS using 1000 shots. In this case, Aspen-11 performed at 7512 CLOPS and Aspen-M performed at 8333 CLOPS, demonstrating that comparable or better system speed persists at both higher shot counts and higher qubit counts. These speed tests were conducted using the production Rigetti QCS environment.[i]”

As IBM’s Katie Pizzolato (director, quantum theory & applications systems) noted at IBM’s Quantum Summit late last year: “There’s no getting away from it. Useful quantum computing requires running lots of circuits. Most applications require running at least a billion. If it takes my system more than five milliseconds to run a circuit, it’s simple math, a billion circuits will take you 58 days; that’s not useful quantum computing.”

Rigetti founder and CEO Chad Rigetti said in the announcement: “Last year we introduced the world to our proprietary multi-chip technology. We believe our approach to building quantum computers has tremendous advantages, including allowing us to meet the challenges of scaling to systems capable of solving real-world problems. Aspen-M is our first commercial system based on this multi-chip technology. Today, we are excited to make Aspen-M generally available to our customers and to release the initial results of system speed tests run on Aspen-M through our production platform.”

Rigetti’s deal with Nasdaq is also significant. Financial services applications are expected to be among the low-hanging fruit for quantum computing. Secure communication, anchored by quantum key distribution technology is one likely use, but so are optimization functions and risk assessment applications. Nasdaq is home to many tech stocks and has a reputation for being an early adopter of technology.

The collaboration will leverage use of Rigetti’s new Aspen-M multi-chip processor and focus on “machine learning, optimization and simulation problems with Nasdaq’s market perspective, domain expertise and data,” say the companies. The collaboration will evaluate financial applications that “may benefit from the ability of quantum computing to solve computational problems with improved accuracy, speed, or cost.”

Fraud detection, order matching and risk management are cited as key targets. The two companies “are expected to pursue the development of algorithms and software with the goal of demonstrating the advantages of hybrid quantum-classical computers for solving the identified problems,” according to the announcement.

Lastly, Rigetti and Ampere today announced a strategic partnership to create hybrid quantum-classical computers designed to unlock a new generation of machine learning applications over the cloud.

According to the announcement, “The two companies will integrate Rigetti Quantum Processing Units (QPUs) with Ampere Altra Max cloud-native processors to create a hybrid computing environment intended to meet the rigorous demands of machine learning applications. This tight coupling of processing power has the goal of enabling the discovery and deployment of high performance machine learning algorithms, with Ampere Altra Max powered cloud servers expected to process vast amounts of data in concert with quantum calculations performed on Rigetti QPUs.”

This is an interesting deal; it gets Arm into the quantum game. Intel (x86 architecture) has long had a quantum effort that is developing both quantum processor technology based on silicon dots (spin-based qubits) and specialized cryo-controller chips. Intel has said it plans to leverage its CMOS manufacturing technology to scale its efforts. IBM likewise has both quantum and silicon chip expertise.

Renee James, Ampere’s founder and CEO, said, “Our collaboration with Rigetti is a natural extension of our strategy to create cloud native processors optimized for a wide range of workloads and customer needs. Quantum machine learning is emerging as a significant opportunity for scientific computing users and their providers of public and private clouds. We believe that Ampere and Rigetti will enable quantum computations of increased complexity, with the potential for higher performance at lower costs.”

The two companies “anticipate working together to optimize quantum computer simulation software to run on Ampere Altra Max processors. Quantum computer simulators enable developers to study and benchmark algorithms and applications by executing quantum circuits on classical computers before running the programs on actual quantum computers. With a simulator optimized for Altra Max, it is expected that Rigetti customers will have the ability to build and test quantum computations of increased complexity, with higher performance, at lower costs.”

Today, financial services giant JPMorgan Chase, chip and systems giant Toshiba, and networking power Ciena reported demonstrating “full viability of a first-of-its-kind Quantum Key Distribution (QKD) network for metropolitan areas, resistant to quantum computing attacks and capable of supporting 800 Gbps data rates.”

Quantum key distribution (QKD), of course, isn’t new, but it is increasingly important as modern classical computers get better at decryption and as we approach practical quantum computers that should be able to crack any existing codes. The critical prevention step is being able to detect any attempt to intercept and read encryption keys quickly and easily. QKD does this by using quantum-encoded photons, which are encoded such that an attempt to “listen in” (measure them) changes the photons and is instantly detected.

As described by a JPMorgan spokesman: “The measurement of photons transmitted in a fiber optic channel are used to generate keys, that are then exchanged and synchronized by a pair of QKD servers and used by cryptographic algorithms to encrypt and decrypt the information. The main security benefit behind QKD is the ability of the two communicating parties to detect disturbances in the fiber (e.g. eavesdropping attempts) enabling them to take appropriate action.” (Here’s a brief description of QKD.)

The collaborators published a paper today describing their work. Here’s portion of the abstract:

“To the best of our knowledge, this is the first time that an 800 Gbps quantum-secured optical channel—along with several other Dense Wavelength Division Multiplexed (DWDM) channels on the C-band and multiplexed with the QKD channel on the O- band—was established at distances up to 100 km, with secure-key rates relevant for practical industry use cases. In addition, during the course of these trials, transporting a blockchain application over this established channel was utilized as a demonstration of securing a financial transaction in transit over a quantum-secured optical channel.

“In a real-world operational environment, deployment of such high-capacity quantum-secured optical channels multiplexed with the quantum channel will inevitably introduce challenges due to their strict requirements, such as high launch powers and polarization fluctuations. Therefore, in the course of this re- search, experimental studies were conducted on the impact on the system performance—and specifically on the quantum channel—of several degradation factors present in real-world operational environments, including inter-channel interference (due to Raman scattering and nonlinear effects), attenuation, polarization fluctuations and distance dependency. The findings of this research pave the way towards the deployment of QKD- secured optical channels in high-capacity, metro-scale, mission- critical operational environments, such as Inter-Data Center Interconnects.”

Figures from the paper showing the experiment setup are below. Click to enlarge.

The work used a QKD-secured optical channel to deploy and secure Liink by J.P. Morgan, which JPMorgan describes as a production-grade, peer-to-peer blockchain network. Snapshot of the results:

Marco Pistoia, distinguished engineer and head of the JPMorgan Chase’s FLARE (Future Lab for Applied Research and Engineering) is quoted in the release: “This work comes at an important time as we continue to prepare for the introduction of production-quality quantum computers, which will change the security landscape of technologies like blockchain and cryptocurrency in the foreseeable future.”

CU Boulder adds four industry partners to CUbit

Three companies – Atom Computing, ColdQuanta and Meadowlark Optics – and SPIE (the international society for optics and photonics) joined University of Colorado’s (CU Boulder) CUbit Quantum Initiative as members of its partners’ program. Regional efforts such CQI have been sprouting up around the country, seeking to leverage academic and commercial resources to develop quantum computing and quantum information sciences.

The partners program, according to CQI, is intended to cultivate “mutually beneficial collaborations with quantum-intensive enterprises.” No specific projects were cited, but the broad idea is to “accelerate CU Boulder’s quantum efforts, including through providing unique insights related to research and training, collaborating on workforce development programs, and providing real-world opportunities for CU Boulder students, postdocs and researchers.”

“We’re tremendously excited to welcome the first CUbit Innovation Partners as we launch our corporate partnership program,” said Philip Makotyn, executive director of the CUbit Quantum Initiative. “Building on existing close relationships, the program is an important step bringing together academics, national labs and industry to build a strong quantum ecosystem. The new members represent an important step supporting the national priority of quantum technologies.”

“Atom Computing has joined forces with the CUbit Quantum Initiative to drive critical R&D and talent development in Quantum Information Science,” said Rob Hays, CEO, Atom Computing. “As a member of the CUbit Advisory board, we will leverage our deep ties across CU Boulder and collaboration with other ecosystem players as a springboard to accelerate large-scale quantum computing, helping researchers and scientists reach their next big breakthrough.” Hays also has posted a blog about the partnership.

Classiq raises $33M in Series B round

Founded in May 2020, Tel Aviv-based Classiq is one of many young quantum software companies working to develop tools to ease and speed development of algorithms for use on quantum hardware. Today, it reported raising $33 million in a Series B round, which the company touts as “another sign that the world is moving from quantum exploration to quantum production – and that quantum software development is a key ingredient in gaining quantum advantage.” Indeed, Classiq is part of the rapid expansion of the quantum computing ecosystem.

Investors, according to Classiq, include: “Hewlett Packard Pathfinder, the venture capital program of Hewlett Packard Enterprise (HPE); Phoenix, a $60-billion insurance company; Spike Ventures, a Stanford alumni investor group; and Samsung NEXT, the investment arm of Samsung are new investors in the company. This round also included personal investments from Lip-Bu Tan and  Harvey Jones, joining existing investors Wing VC, Team8, Entrée Capital, Sumitomo Corp. (through IN Venture) and OurCrowd. This new round brings Classiq’s total funding to $48 million in 20 months of existence.”

“We welcome our new investors and are grateful for the continued support of our existing ones. Together, we are paving the fastest way towards quantum advantage and the only way beyond it,” said Nir Minerbi, co-founder and CEO at Classiq. “This new funding comes at a pivotal time. The quantum industry is now moving from consulting services to quantum products and from prototyping to production. With this funding, we will expand upon our work to become the platform on which forward-thinking organizations develop game-changing quantum software that makes the impossible possible.”

Classiq says it will use the new funds to quadruple the size of the company by expanding its team of world-class engineers and researchers, opening new offices around the globe, and continuing to develop and file revolutionary quantum algorithm design patents.

Paul Glaser, vice president and head of Hewlett Packard Pathfinder, is quoted as saying, “We were impressed by Classiq’s novel synthesis engine that automates the creation of quantum circuits and leads to significantly lower barriers of entry for quantum computing.”

Boaz Morris, investment manager at Phoenix, said, “While quantum hardware has made impressive progress, the software used to operate these advanced computers remains woefully inadequate. Classiq’s hardware-agnostic platform enables enterprises to develop sophisticated quantum software faster and better than any other method. We are thrilled to partner with the world-class team at Classiq as they continue to execute on their vision and become the leader in the quantum software stack.”

Israel Defense Ministry plans quantum computing investment

Government funding spigots throughout the world are being opened to advance quantum computing and avoid losing ground to rivals. Now, a report yesterday in The Times of Israel has said that the “Israeli Innovation Authority and the Defense Ministry will spend approximately NIS 200 million ($62 million) to develop Israel’s first quantum computer and lay the foundation for Israeli computational ability, which they said would lead to future developments in economics, technology, security, engineering, and science.”

According to the article, “[T]he budget will fund two parallel avenues. The Israel Innovation Authority will focus on developing the infrastructure for quantum computational ability which, it said, may include the use of technology from abroad. The Defense Ministry’s Directorate of Defense Research and Development (DDR&D), meanwhile, will establish a national center with quantum capabilities that will work with academia, industry, and government partners to develop a quantum processor and then a complete quantum computer.”

IonQ and Pacific Northwest National Laboratory today reported generating a “sustainable and robust source of barium qubits” for IonQ’s next-generation quantum computers. IonQ believes that this collaboration will supply barium qubits for its quantum computers in perpetuity, a key step as the company begins to scale its manufacturing operations. Rigetti today reported it achieved “entangling gate fidelities as high as 99.5% on its next-generation chip architecture,” crossing what is believed to be a key threshold for commercial quantum computing.

[i] CLOPS is calculated as M × K × S × D / time taken where: M = number of templates = 100; K = number of parameter updates = 10; S = number of shots = 100 (or 1000); and D = number of QV layers = log2 QV.  To Rigetti’s knowledge, CLOPS as a speed test has not been investigated or verified by any independent third party.  In addition, while Rigetti applied the above formula in testing the speed of Aspen-M and Aspen-11, there is no guarantee that Rigetti applied the test in the same way as IBM and, as a result, any variability in the application of the test as between Rigetti, IBM or others in the industry that may apply CLOPS in the future could render CLOPS scores incomparable and actual relative performance may materially differ from reported results.
