System Model H2: Accelerating your path to fault-tolerant quantum computing
A quantum revolution 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 computers with a new racetrack-shaped trap. Featuring 32 fully-connected qubits and an all-new architecture, Quantinuum’s H2 provides a quantum volume of 65,536 (216).
Quantinuum’s System Model H2 includes numerous hallmark features that set it apart from other types of quantum computers, including:
32
fully-connected qubits
65,536 (216)
Quantum Volume
99.997%
single-qubit gate fidelity
99.8%
two-qubit gate fidelity
- All-to-all connectivity
- Qubit reuse
- Mid-circuit measurement with conditional logic
How does it feel to have achieved this milestone?
“I’ve been working on the H2 system for the past 2 years, so it’s really exciting and gratifying to finally see all of our hard work pay off and launch a groundbreaking system we can be incredibly proud of."
What does access to the H2 mean for users/customers?
“H2 users will have access to a quantum computer with enough qubits to start burdening classical simulations (our classical emulator is now slower than our quantum computer), with operational fidelities at the same high level that Quantinuum customers have come to expect from our hardware. This combination of more qubits at world-class fidelities will expand the depth and breadth of what our customers can do with our systems.”
How does it feel to have achieved this milestone?
“Launching H2 is the culmination of several years of hard work by a very talented team, and it’s wonderful to see all the pieces of such a complex project come together.”
What does this upgrade mean for users/customers?
“Users and customers of H2 will have the opportunity to test algorithms on one of the most powerful quantum computers ever developed. I’m excited to see how quantum error correction protocols evolve and mature due to work on the H2 machine.”
How does it feel to have achieved this milestone?
“Historic. This is a major proof point of the overarching goal of QCCD: scale qubit number while maintaining gate fidelity.”
What does this upgrade mean for users/customers?
“With H2 customers will begin to realize how beneficial all-to-all connectivity is as qubit numbers scale. Specifically, entangling distant qubits won’t come at the cost the error incurred from additional gates.”
