Quantinuum Sets Industry Record for Hardware Performance with New Quantum Volume Milestone

Customers the first to benefit as Quantinuum extends its lead in full-system quantum computing performance

February 23, 2023

Broomfield, Colorado, February 23rd, 2023Quantinuum, the world’s largest standalone integrated quantum computing company, today announced its H1 generation quantum processors set two performance records in quick succession, with its H1-1 achieving a quantum volume (QV) of 16,384 (214), and then 32,768 (215). The achievements represent a high-water mark for the quantum computing industry, based on the widely recognized QV benchmark, which was originally developed by IBM to reflect a quantum computer’s general capability.

“Quantum volume is crucial to the ongoing development and research necessary to create the bigger and better quantum computers needed to achieve a quantum advantage,” said Paul Smith-Goodson, Analyst, Moor Insights and Strategy. “Quantinuum has prioritized increasing its quantum volume since the start, which has not only benefitted its current applications but set itself up to be the benchmark in achieving quantum advantage.”

This marks the eighth time in less than three years that Quantinuum’s H-Series, which is based on quantum charge coupled device technology, has set an industry benchmark, and fulfills a public commitment made in March 2020 to increase the performance of the H-Series quantum processors, Powered by Honeywell, by an order of magnitude each year for five years.

“This is a remarkable milestone for quantum computing and inline with the technology we have seen from Quantinuum,” said Marco Pistoia, Ph.D., Distinguished Engineer and Head of Global Technology Applied Research, JPMorgan Chase. “As evidenced in our research, we have produced groundbreaking algorithms on their quantum computers for the past several years, which has allowed us at JPMorgan Chase to be on the leading edge of quantum computing. We look forward to continuing to make more breakthroughs in quantum computing together.”

To provide more detail on the underlying technological improvements that led to the new benchmark, Quantinuum revealed details of recent performance enhancements to the H-Series, including reductions in the phase noise of the device’s lasers, reducing two-qubit gate error and memory error, and improvements to elements of the calibration process. Scientists at Quantinuum also shared insights into how the improvements that resulted in the new benchmark reduce the time it takes for algorithms to run, improve the ability to run quantum error correction codes, and lead to better results for the scientists and researchers using the H-Series hardware.

“We are exactly where we expect to be on our roadmap,” said Tony Uttley, President and COO of Quantinuum. “Our hardware team continues to deliver technical improvements right across the board, and our approach of continuously upgrading our quantum computers means that these are felt immediately by our customers.”

A five-digit QV number is very positive for real-time quantum error correction (QEC) because of the low error rates, number of qubits, and very long circuits. QEC is a critical ingredient to large-scale quantum computing and the sooner it can be explored on today’s hardware, the faster it can be demonstrated at large-scale.

“With the technology improving fast, we do everything we can to help our customers and the community understand how we are achieving such rapid progress,” said Jenni Strabley, Senior Director of Offering Management at Quantinuum. “Which is why we have published the data behind the results we announced today. Our goal is to accelerate quantum computing, and that is something we can only achieve as an industry.”

Quantinuum and SoftBank Corp. Publish Joint White Paper on Scaling Practical Quantum Computing Use Cases Toward the Fault-Tolerant Era
  • The companies have published a joint white paper mapping commercially relevant quantum computing use cases in quantum chemistry and graph analytics to Quantinuum’s hardware roadmap.
  • The paper provides a framework for assessing how advances in quantum hardware and algorithms could affect when practical industrial applications become feasible.
  • SoftBank Corp. and Quantinuum will use the roadmap to inform their exploration of future quantum AI data center services and related business models.

TOKYO and BROOMFIELD, Colo. – Quantinuum (NASDAQ: QNT) and SoftBank Corp. ("SoftBank") today announced the publication of “Quantum Computing Frontiers,” a joint white paper that maps two commercially-relevant quantum computing application areas against Quantinuum’s hardware roadmap. The analysis examines how advances in quantum hardware and algorithms could affect when these applications become practical for industrial use.

Building on this use-case roadmap, the paper also examines how quantum computing, AI, and high-performance computing could be integrated into future computing infrastructure. It considers how progress across successive hardware generations could inform future quantum AI data center services and related business models, a key focus of the Quantinuum and SoftBank partnership announced last year.

“The key takeaway of this study is that organizations do not need to wait for large-scale, fault-tolerant systems to explore where quantum computing can begin creating value,” said Duncan Jones, General Manager, Applications Group at Quantinuum. “By using today’s systems to develop, benchmark and refine applications in areas such as quantum chemistry and graph analytics, enterprises can build the technical and operational readiness needed for the next era of quantum-enabled computing.”

“The question is no longer whether quantum computing may deliver value, but rather which problem classes become executable at which stage of hardware maturity,” said Ryuji Wakikawa, Senior Vice President & CTO at SoftBank Corp. “However, we believe progress in hardware must be complemented by equally strong developments in quantum algorithms and the integration of quantum systems with AI and high-performance computing.”

The white paper discusses illustrative scenarios describing how representative applications, technology maturity, and potential market opportunities may evolve over time under stated assumptions. The analysis provided in the paper is intended to provide a conceptual framework for understanding potential market evolution and does not represent financial guidance or forecasts. These analyses are intended to support discussion of future technology development and should not be interpreted as commitments regarding commercialization, infrastructure investment, products, services, or financial performance.

The full white paper is available to download on the SoftBank and Quantinuum websites.
