The Future of Quantum Hardware

Delivering 10X the Quantum Performance Each Year

Quantinuum H-Series

The System Model H1, Powered by Honeywell, is our first generation quantum computer. Since being released in 2020, H1 has improved its Quantum Volume from QV = 128 to QV = 32,768, and is the first quantum computer to set numerous quantum volume records on its path to current performance of 32,768. System Model H1 features industry-leading performance and unique capabilities such as all-to-all connectivity, mid-circuit measurement, conditional logic, and qubit reuse.

The System Model H2, Powered by Honeywell, is our second generation of quantum computers with a new racetrack-shaped trap. Featuring 32 fully-connected qubits, we show that Quantinuum's QCCD architecture can scale up in qubit number without reducing the gate fidelities or trading-off on the unique capabilities.   Quantinuum’s H2 provides the world's highest quantum volume of 65,536 (216) and the maintains the highest commercially available two-qubit gate fidelity of 99.8%.

Building Economic Value

Quantinuum has a unique model for hardware development. We are accelerating the economic value of the computer. Customers have access to our most powerful machines which means they take advantage of our continuous upgrade of fidelity, quantum volume, speed, and the number of qubits.

The Power of Quantum Volume

Quantum Volume is a measurement created by IBM. Generally, the larger the Quantum Volume of a quantum computer, the more complex the problems a computer can solve. Quantum performance is not about how many qubits you have, it’s about how effective your qubits are.

The Quantum Volume of the System Model H2, Powered by Honeywell, has been measured at 65,536 and the Quantum Volume of the System Model H1, Powered by Honeywell, has been measured at 32,768.

Why Trapped-ion Quantum Computing?

We have focused on trapped-ion computing because the architecture allows for maximum flexibility in algorithmic design by employing short chains of ytterbium and barium ions. It is so precise that it takes into account the earth’s magnetic field on a surface the size of a thumbnail, yielding a two-qubit gate fidelity of 99.8%.

In addition, our hardware architecture allows for mid-circuit measurement. You can pause your algorithm in the middle of execution to measure the qubits without affecting the final outcome. No other system on the market today allows for such a feat.

Finally, our hardware provides “all-to-all connectivity,” which allows us to move and reuse qubits with unparalleled efficiency, reduce computational steps and overhead, and thereby accumulate fewer errors.
