Quantinuum Launches Industry-First, Trapped-Ion 56-Qubit Quantum Computer, Breaking Key Benchmark Record
Quantinuum and JPMorgan Chase achieved a 100x improvement over the existing industry benchmark using Quantinuum’s H2-1 quantum computer
Broomfield, Colorado and London, UK, June 5th, 2024 — Quantinuum, the world’s largest integrated quantum computing company, today unveiled the industry’s first quantum computer with 56 trapped-ion qubits. H2-1 has further enhanced its market-leading fidelity and is now impossible for a classical computer to fully simulate.
A joint team from Quantinuum and JPMorgan Chase ran a Random Circuit Sampling (RCS) algorithm, achieving a remarkable 100x improvement over prior industry results from Google in 2019 and setting a new world record for the cross entropy benchmark. H2-1’s combination of scale and hardware fidelity makes it difficult for today’s most powerful supercomputers and other quantum computing architectures to match this result.
“We’re extending our lead in the race towards fault tolerant quantum computing, accelerating research for customers like JPMorgan Chase in ways that aren’t possible with any other technology,” said Rajeeb Hazra, CEO of Quantinuum. “Our focus on quality of qubits versus quantity of qubits is changing what’s possible, and bringing us closer to the long-awaited commercialization of quantum’s applications across industries like finance, logistics, transportation and chemistry.”
Quantinuum’s analysis also indicates that the H2-1 executes RCS at 56 qubits with an estimated 30,000x reduction in power consumption compared to classical supercomputers, reinforcing it as the preferred solution for a wide array of computational challenges.
“The fidelity achieved in our random circuit sampling experiment shows unprecedented system-level performance of the Quantinuum quantum computer. We are excited to leverage this high fidelity to advance the field of quantum algorithms for industrial use cases broadly, and financial use cases in particular,” said Marco Pistoia, Head of Global Technology Applied Research at JPMorgan Chase.
Today’s announcement is the latest in a string of breakthroughs made by Quantinuum in 2024:
- In March, the company revealed a long-sought solution to the “wiring problem”, demonstrating that the quantum charge-coupled device (QCCD) architecture can scale to large qubit numbers.
- Quantinuum’s H-Series became the first to achieve “three 9s” – 99.9% – two-qubit gate fidelity across all qubit pairs in a production device, a critical milestone enabling fault-tolerance.
- Then, in collaboration with Microsoft, Quantinuum ’s H2-1 was declared the first – and so far the only – quantum computer capable of achieving Level 2 Resilient quantum computing, creating four reliable logical qubits using error correction and detection to achieve an 800-fold reduction in error rate.
“Microsoft looks forward to a continued collaboration with Quantinuum as they release their high fidelity 56-qubit machine,” said Dennis Tom, General Manager Microsoft Azure Quantum. “Recently, the teams created four highly reliable logical qubits by applying Azure Quantum's qubit-virtualization system to Quantinuum's 32-qubit machine. With the additional physical qubits available on Quantinuum's new machine, we anticipate creating more logical qubits with even lower error rates. As we reach these milestones, we will continue to increase the resiliency of quantum operations as well as the utility of quantum computing.”
Quantinuum also recently closed a $300 million equity fundraise anchored by JPMorgan Chase with additional participation from Mitsui & Co., Amgen and Honeywell, which remains the company’s majority shareholder, bringing the total capital raised by Quantinuum since inception to approximately $625 million.

- The companies plan to continue their co-creation partnership to advance future mobility
- BMW to access the latest generations of Quantinuum systems throughout the partnership
- Advanced materials science research supports a range of next-generation technologies
Broomfield, Colorado, May 5th, 2026 — Quantinuum and BMW Group have formally expanded their ongoing collaboration into a multi-year partnership with a mission to unlock future mobility by applying quantum computing toward advanced materials science.
Since 2021, Quantinuum and BMW Group have been collaborating on joint research focused on tackling complex challenges in industrial chemistry to support the advancement of next-generation mobility. The collaboration has progressed from foundational algorithm development to advanced simulations of molecular systems, allowing the researchers to unlock insights into catalytic activity, reaction pathways, and material performance in energy-relevant environments.
The companies have now agreed to extend the work, positioning the alliance to become one of the longest-sustained commitments between a commercial enterprise and a quantum computing provider to date.
“Quantinuum is focused on driving commercial adoption of quantum computing through close collaboration with industry leaders on high-impact applications," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Our expanded partnership with the BMW Group underscores this focus, and we’re excited to scale the meaningful work we’ve been advancing together.”
Researchers at BMW Group are utilizing Quantinuum's trapped-ion architecture, which provides the high-fidelity operations necessary to accurately simulate molecular systems, particularly electrochemical processes that play a critical role across a range of technologies relevant to sustainable mobility and the design and optimization of fuel cells.
Under the terms of the agreement, BMW Group will leverage successive generations of Quantinuum’s quantum computers. This includes the current Helios system and upcoming generations, Sol (planned for 2027) and Apollo (planned for 2029). This will enable the teams to validate progress at each stage while scaling toward industrially meaningful solutions.
“We have been exploring quantum computing for many years,” said Dr. Martin Tietze, Vice President of New Technologies at BMW Group. “Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations.”
Quantinuum’s progress toward large-scale, fault-tolerant systems helps to ensure that as the hardware reaches milestones in performance, BMW can apply that computational power to catalyst chemistry research, targeting critical oxygen reduction reaction processes at platinum catalysts to potentially lower costs and improve energy efficiency.
The companies broke new ground in 2024, alongside another commercial partner, as the first to simulate catalytic performance using a quantum computer with results published in Nature Partner Journal.
Beyond its technical achievements, the collaboration has evolved into a deeply connected, cross-disciplinary effort, bringing together quantum scientists, chemists, and engineers in a sustained partnership that reflects both the complexity of the challenge and the scale of the ambition.
