System Model H2: Challenging the limits of classical computing
Fault-tolerant quantum computing is on the horizon
Entering a New Phase of Quantum Computing with our Second-generation System
The System Model H2, Powered by Honeywell, is our latest generation of quantum computer. Featuring 56 fully-connected, high-fidelity qubits and a quantum volume of 262,144 (218), Quantinuum’s H2 processor is now impossible to fully simulate classically.
Quantinuum’s System Model H2 includes numerous hallmark features that set it apart from other quantum computers, including:
56

two-qubit gate fidelity
- Highest commercially available two-qubit gate fidelity
- All-to-all connectivity
- Qubit reuse
- Mid-circuit measurement with conditional logic
What is your role?
“I've been on the H2 team for three and a half years helping build up the system, and I'm currently focused on optimizing the performance and finding new ways to improve the fidelity of the H2 system.”
How does it feel to have achieved N=56?
“Being on the team to run the first quantum circuit with trapped ions with complexity beyond that of the world's most powerful classical computers has been incredibly exciting, and it's an honor to work among all the great scientists who have made this achievement possible.”
What does the N=56 upgrade mean for users/customers?
“The H2 system has always offered industry-leading fidelities. By scaling up to 56 qubits while maintaining (and even improving on) fidelity, an entirely new class of extremely complex circuits can be run with unprecedented fidelity.”
What is your role?
“I am in charge of overseeing the transition of bringing new systems online.”
How does it feel to have achieved N=56?
“The upgrade of H2-1 is a major achievement of which the entire Quantinuum organization should be proud.”
What does the N=56 upgrade mean for users/customers?
“We now have more qubits than ever before, while still maintaining the high fidelities users expect from Quantinuum. This is a machine that can do incredible things!”
What is your role?
“I work on ion transport waveform development, testing, and implementation for H2.”
How does it feel to have achieved N=56?
“A lot of transport optimization, and completely rethinking transport operations went into this project to expand the capability of the H2 trap. Having it all succeed feels amazing, and I am extremely proud to have been a part of the team that brought it all together.”
What does the N=56 upgrade mean for users/customers?
“This N=56 upgrade scales up the qubit number of the H2 system to fully utilize the space offered by the H2 trap without any reduction in the world class all-to-all connectivity and gate performance Quantinuum is known for. This upgrade provides users with a real playground to explore in, opening the doors to probe deeper and more complex problems than ever before.”
