Quantinuum Highlights the latest performance of the H-Series Quantum Computer Range.

Quantinuum’s H-Series hardware, powered by Honeywell, developed in collaboration with Honeywell, has significantly improved performance in the last six months. The System Model H1-1 has increased its quantum volume from 16,384 to 524,288, a thousand times higher than the following best-reported quantum volume. The company claims quantum volume data is taken from commercial systems used by customers, ensuring transparency and reliability.

Quantinuum set ambitious goals in 2020 when it launched its first quantum computer, HØ, with six qubits and a quantum volume of 64. The company committed to increasing the quantum volume of its commercial machines tenfold each year for five years, aiming for a quantum volume of 8,388,608 or 223 by the end of 2025. Despite the scepticism often associated with the industry, Quantinuum has consistently achieved world records in its pursuit to improve the performance of its quantum computers. From 2020 to early 2023, the quantum volume has steadily increased, demonstrating that an increased qubit count while reducing errors directly translates to more computational power.

None of the results achieved by Quantinuum were “hero results”, meaning no special calibrations were made just to make the system look better. The quantum volume data is taken from commercial systems interwoven with customer jobs, ensuring that what the company experiences is what its customers experience. The improvement over the past six months has been 30x, accelerating at least one year from the five-year commitment. The progress made on one machine can be easily shared with another due to the similarities in design, ensuring consistent results.

Quantum Volume as a Benchmark?

In the rapidly evolving quantum computing industry, disagreements exist about which benchmarks are best to use. Quantum volume, developed by IBM, is a rigorous and peer-reviewed benchmark that can be measured on any gate-based machine. Improvements in quantum volume require consistent reductions in errors, making it likely that no matter the application, quantum volume improvements translate to better performance. Quantinuum has adopted quantum volume as its primary system-wide benchmark to report its performance. However there are plenty of other developers of quantum systems who are keen on a more simple metric: qubit count. For one thing, whilst Quantum Volume measures multiple parameters and qubit count does not, qubit count does at least offer some amazing simplicity when it comes down to benchmarks.

Micro Summary
