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.

Santa Clara, Calif. – March 18, 2025 – Quantinuum, the industry leader in quantum computing with the world’s highest performing quantum computer, will work with NVIDIA as a founding collaborator on breakthroughs at the NVIDIA Accelerated Quantum Research Center, where operations are expected to begin later this year.
NVIDIA Accelerated Quantum Computing Research Center (NVAQC) will provide the ability to develop quantum solutions and applications that help solve some of the world’s most pressing problems. The center will accomplish this by using NVIDIA CUDA-Q platform alongside a world leading NVIDIA GB200 NVL72 supercomputer with Quantinuum’s System H2, which achieves 2,097,152 Quantum Volume — orders of magnitude greater than the next best available.
Quantinuum’s quantum computing architecture delivers the fastest time-to-solution available and is positioned to extend this leadership with its next-generation systems. By 2027, Quantinuum will launch the industry’s first 100-logical-qubit system, featuring best-in-class error rates. The company is also on track to deliver commercially scalable quantum computers with hundreds of logical qubits by the end of the decade. This progress builds upon a series of recent technology breakthroughs, including Quantinuum’s creation of the most reliable and highest-quality logical qubits, as well as solving the key scalability challenge associated with ion-trap quantum computers — culminating in a commercial system with greater than 99.9% two-qubit gate fidelity.
In 2022, Quantinuum became the first company to bring CUDA-Q to its Quantum systems, establishing a pioneering collaboration that continues to advance the platform today in multiple areas including application development and Quantum Error Correction (QEC). Users of CUDA-Q are currently offered access to Quantinuum’s System H1 QPU and emulator for 90 days. Quantinuum’s future systems will continue to support the CUDA-Q platform and be available via the NVAQC, accelerating the adoption of Generative Quantum AI (Gen QAI).
Quantinuum’s groundbreaking Gen QAI system, announced last month, enables data generated by Quantinuum’s quantum systems to be harnessed to train AI systems, significantly enhancing the fidelity of AI models, and allowing them to tackle challenges previously deemed unsolvable. Through this achievement, Quantinuum is setting a new standard for AI training and problem-solving across various industries.
“By combining NVIDIA's AI hardware and software solutions with leading and differentiated solutions from Quantinuum, we’re unlocking unprecedented solutions and accelerating Generative Quantum AI’s adoption across diverse markets,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum.
"Progress toward useful quantum computing hinges on new discoveries," said Tim Costa, Senior Director of CAE, Quantum, and CUDA-X at NVIDIA. "The NVAQC will fast-track the development of useful quantum devices, being the epicenter for breakthroughs made with partners like Quantinuum."
