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’s ‘Quantum Origin’ Becomes First Software Quantum Random Number Generator to Achieve NIST Validation

Broomfield, CO – April 2nd, 2025 — Quantinuum, the industry leader in quantum computing with the world’s highest performing quantum computer, today announced that  Quantum Origin, the company’s software Quantum Random Number Generator (QRNG), has received National Institute of Standards and Technology (NIST) validation. Quantum Origin is the first software QRNG to achieve this validation, establishing it as a crucial tool for federal agencies and agency partners in their mandated migration to post-quantum cryptography (PQC) under National Security Memorandum 10. This achievement will help strengthen cybersecurity in the age of PQC.

Quantum Origin generates mathematically proven randomness — a capability unmatched by hardware-based QRNGs or traditional pseudo-random number generators. Unlike hardware solutions that require specialized equipment and can be affected by environmental factors, Quantum Origin delivers consistent, proven randomness through flexible software deployment. Proven quantum randomness is an essential foundation for comprehensive quantum security strategy alongside PQC.

"The evolving threat landscape demands a new era of cybersecurity solutions for governments, enterprises, and critical infrastructure," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. "Quantinuum is at the forefront of this transformation, driving innovation in quantum cybersecurity. Our recent certified randomness demonstration with JPMorganChase, and our NIST-validated Quantum Origin platform are just two examples of how we are deepening our portfolio to meet this critical need."

Quantum Origin is delivered entirely as self-contained software, making it adaptable to diverse environments from cloud solutions to highly sensitive systems. It can be deployed with zero network connectivity, enabling protection for air-gapped networks and confidential environments where traditional hardware-based QRNGs cannot operate effectively. It provides quantum-enhanced security without impacting the size, weight, and power (SWaP) requirements of existing systems, a critical consideration for resource-constrained deployments.

U.S. Made using Quantinuum's quantum computers based in Colorado, Quantum Origin helps mitigate supply chain risks associated with foreign-sourced hardware components. It is designed to integrate seamlessly with existing NIST-approved cryptographic systems without requiring recertification. With this NIST validation, organizations can now accelerate their adoption of quantum-enhanced security within existing compliance frameworks.
