Quantinuum Completes Hardware Upgrade; Achieves 20 Fully Connected Qubits

The newly upgraded H1-1 quantum computer has undergone extensive testing to verify performance and functionality, including by customer JPMorgan Chase, which has published its results

June 14, 2022

Broomfield, Colorado, June 14th, 2022 Quantinuum today announced a major upgrade to its System Model H1 technology that includes expanding to 20 fully connected qubits and increasing the number of quantum operations that can be completed in parallel.

The improvements significantly bolster the computational capabilities of the H1-1 quantum computer, Powered by Honeywell, which has set numerous industry records for quantum volume, a measure of overall performance, since debuting in fall 2020.

“With these upgrades, developers are able to run more complex calculations than they could before, without sacrificing performance,” said Tony Uttley, Quantinuum’s President and Chief Operating Officer. “This upgrade is yet another example of our unique business model of continuously upgrading our systems, even after they are in commercial use, to provide the best performance to our users.”

The upgraded system has undergone extensive testing by internal and external users to verify performance and functionality, including a private preview with JPMorgan Chase.

“The quantum computing team at JPMorgan Chase has been using Quantinuum’s quantum computer to run experiments that use mid-circuit measurement and reuse and quantum conditional logic, taking advantage of the computer’s very high quantum volume,” said Marco Pistoia, Ph.D., Distinguished Engineer and Head of Quantum Computing and Communication Research in the bank. “In our experiments, we used the 20 qubits of the H1-1 computer on a quantum Natural Language Processing algorithm for extractive text summarization. The results were almost identical to the reference values computed with a noiseless simulator, validating the computer’s high fidelity, as shown in our recent arXiv preprint. Thanks to this, the Quantinuum computer continues to be an essential resource for our research in Quantum Computing.”

Several upgrades were made by the Quantinuum team to the H1-1 machine, including:

  • Increasing the number of fully connected qubits from 12 to 20 while simultaneously preserving its low two-qubit gate errors (typical performance fidelities of 99.7 percent with fidelities as high as 99.8 percent) and critical features such as mid-circuit measurement, qubit reuse, quantum conditional logic and all-to-all connectivity.
  • Increasing the number of gate zones from three to five, enabling the H1-1 to complete more quantum operations simultaneously and allowing increased parallelization in circuit execution.

Uttley said such upgrades prove an important next step in the H-Series roadmap - the ability to increase the qubit count and number of gate zones without compromising gate fidelity.

The second version of the System Model H1, the H1-2, is scheduled to undergo similar upgrades later this year.

“These latest advances show that we understand what it takes to scale our trapped-ion quantum hardware and that we’re continuing to make the expected progress on our technology roadmap,” Uttley said. “We are adding qubits and maintaining fidelity without compromising any features, which is absolutely essential as we scale to our future H-Series generations.”

Quantinuum uses the System Model H1 machines to develop fully integrated solutions such as Quantum Origin, its cybersecurity offering, and InQuanto, its recently released quantum computational chemistry software. (Access to the H1 machines is offered with licenses to InQuanto software.)

Quantinuum also provides commercial access to its trapped ion quantum computers H1-1 and H1-2, as well as the H1 Emulators through Microsoft’s Azure Quantum.

“The continuous upgrading of Quantinuum’s systems has been a great benefit to Microsoft customers. Microsoft is pleased to offer the new capabilities of H1-1 with 20 qubits to customers who access Quantinuum's H-Series Systems through Microsoft Azure Quantum and our Azure Quantum Credits program which provides free access to quantum hardware for customers,” said Fabrice Frachon Azure Quantum Principal Program Manager.

Quantinuum, Rolls-Royce, Riverlane and University of Edinburgh Sign Agreement to Explore Quantum Computing for Industrial Design and Simulation
  • Collaboration will explore how fault-tolerant quantum computing could advance complex fluid dynamics simulations, including for uses in gas turbine design
  • Project aims to combine Quantinuum’s Helios platform, the world’s most accurate commercial quantum computer1, Rolls-Royce’s industrial applications, Riverlane’s quantum error correction and fault-tolerant algorithm expertise, and EPCC’s supercomputing expertise
  • Collaboration will help advance the UK quantum strategy by developing the quantum technologies and hybrid computing capabilities needed for future industrial applications

BROOMFIELD, Colo. and CAMBRIDGE, UK, July 14th, 2026 – Quantinuum Inc. (NASDAQ:QNT), Rolls-Royce, Riverlane and EPCC, the UK National Supercomputing Centre based at the University of Edinburgh, today announced an agreement to explore the quantum computing capabilities needed in future industrial workflows, such as gas turbine design.

Under the agreement, Quantinuum will provide access to its quantum systems and software environment; Rolls-Royce will contribute industrial design use cases and domain expertise; Riverlane will contribute quantum error correction and algorithmic expertise; and EPCC will contribute supercomputing expertise and hybrid workflow integration.

Complex fluid dynamics simulations are central to gas turbine design, but they can require substantial computing resources as models become more detailed. In what is expected to be a multi-year collaboration, the partners will explore how fault-tolerant quantum computers could work alongside supercomputers to address this bottleneck, and accurately model fluid dynamics inside gas turbines.

“The computing demands of simulating complex fluid dynamics are a major challenge in industrial design, and exploring how quantum computing can complement today’s supercomputers is an important step toward addressing them,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “This collaboration will help develop and test the hybrid quantum-classical algorithms needed for future industrial applications.”

The collaborators plan to test key computational building blocks for industrially relevant quantum algorithms on Quantinuum’s Helios quantum computer and assess how these could scale on planned future systems, such as Sol and Apollo.

This project builds on prior collaborations between Rolls-Royce, Riverlane and EPCC that laid the foundations for understanding key algorithmic, error correction and data requirements for tackling fluid dynamic simulations with commercial quantum computers.

“We have been developing and improving algorithms for hybrid fault-tolerant applications for almost five years with Riverlane, using classical emulators in collaboration with EPCC. This agreement marks the start of an exciting new phase where we work together to explore their implementations on Quantinuum’s hardware,” said Leigh Lapworth, Fellow in Computational Science at Rolls-Royce. “Applications development is a multi-year activity and if we want to be in a position to benefit from teraQuOp devices, we have to start now, co-developing the algorithms, hardware and software.”

“Riverlane specialises in quantum error correction (QEC), as the critical technology that will ultimately unlock large fault tolerant quantum computing, and fault tolerant applications for various industries," said Steve Brierley, CEO and Founder of Riverlane. "Building on our work with Rolls-Royce and EPCC, collaborating with Quantinuum will help us explore how fault-tolerant quantum computing and hybrid quantum-HPC approaches can accelerate the path to industrial quantum computing."

EPCC will contribute its expertise in high-performance computing, simulations and the software interfaces needed to connect quantum and classical systems. Its role includes exploring how different parts of an algorithm can be compiled, emulated and executed across classical and quantum resources, including pre- and post-processing steps required for hybrid compute workflows.

“Quantum computing will be most valuable when users can exploit it within a wider computing environment, and EPCC has been working towards hybrid HPC and quantum since my appointment as a Chancellor’s Fellow in 2023,” said Oliver Thomson Brown, Quantum Group lead at EPCC. “EPCC’s mission is to accelerate the effective use of novel computing across industry and academia, and this project is a natural fit with the goals of the UK’s first National Supercomputing Centre.”

The UK’s quantum computing mission aims to develop accessible, UK-based quantum computers capable of one trillion error-free operations, known as “teraQuOp” systems. The collaboration and its anticipated multi-year timeline support the UK Government’s quantum computing mission and reflect the strength and maturity of the UK’s quantum and advanced computing ecosystem in moving from foundational research toward industrially relevant hybrid applications.
