System Model H2: Accelerating your path to fault-tolerant quantum computing

A quantum revolution is on the horizon

System Model H2

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).

Projects Run on H2

Measuring the Loschmidt amplitude for finite-energy properties of the Fermi-Hubbard model

A joint team of scientists at Quantinuum, NIST, and the University of Maryland have measured the Loschmidt amplitude of the Fermi-Hubbard model, demonstrating a vital tool for understanding enigmatic phases of matter such as superconductivity.

Sequence Processing with Quantum Tensor Networks

For the first time, Quantinuum researchers have run scalable quantum natural language processing (QNLP) models, able to parse and process real-world data, on a quantum computer.

H2 Benchmarking

A Race Track Trapped-Ion Quantum Processor

Quantinuum’s benchmarking assessment of the System Model H2’s performance is considered one of the most thorough assessments of any quantum system to date.

H2 Combinational Optimization

Exploring the neighborhood of 1-layer QAOA with Instantaneous Quantum Polynomial Circuits

Quantinuum’s machine learning team demonstrated a new heuristic optimization routine that can solve optimization problems with minimal quantum resources.

JPMC Paper

Alignment between Initial State and Mixer Improves QAOA Performance for Constrained Portfolio Optimization

Global Technology Applied Research at JPMorgan Chase demonstrated that the performance of the quantum alternating operator ansatz (QAOA) depends on the alignment between the initial state of QAOA and the ground state of the mixing Hamiltonian.

Caroline Figgatt
Senior Advanced Physicist
Project role:  I’m an atomic physicist who focuses on implementing, improving, and maintaining the system control code.

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.”

Project role: Medium and long-term technical direction.

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.”
