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 Selected by DARPA to Advance to Stage B of Quantum Benchmarking Initiative

With the industry's most advanced quantum systems and proven ability to scale, Quantinuum is on track to deliver utility-scale quantum computing by early 2030s 

November 6, 2025 – Broomfield, CO – Quantinuum, the world leader in quantum computing, has been selected by the Defense Advanced Research Projects Agency (DARPA) as a contractor to advance to Stage B of DARPA’s Quantum Benchmarking Initiative (QBI).

DARPA is using QBI to evaluate the technical likelihood that a utility scale quantum computer will be available no later than 2033. A multi-stage program, Stage B follows a six-month Stage A effort in which Quantinuum developed and delivered a detailed concept design for a utility scale system called “Lumos.” 

Last year, Quantinuum released its public roadmap through the end of the decade with Apollo—a universal, fully fault-tolerant quantum computer—scheduled for launch in 2029. Lumos is a new addition to the roadmap as Quantinuum outlines plans to develop increasingly larger systems into the 2030s. 

“This selection recognizes the strength and maturity of our roadmap and the work our teams have already delivered,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Lumos extends our roadmap into the next decade and gives DARPA a concrete, de-risked path for achieving utility-scale quantum computing by 2033. We look forward to partnering with DARPA and our ecosystem partners to advance this important national objective.”

Stage B will be a year-long, performance-based evaluation by DARPA’s Test and Evaluation team in which Quantinuum will develop a detailed R&D roadmap for Lumos to validate technical assumptions, verification methods, and scaling plans to meet the 2033 objective.

Yesterday, Quantinuum deployed its latest generation system, “Helios,” on schedule with its roadmap. With the highest fidelity physical qubits and logical qubits of any commercial system, and a next-generation software stack featuring a modern, high-level programming language, Helios is designed to accelerate quantum computing adoption. The system has already been used to simulate high-temperature superconductivity and magnetism at unprecedented scales—two applications with relevance to critical, industrial utility.
