With 56 qubits, the Quantinuum team conducted experiments to test the performance of their machine. The results, published on June 4 on arXivhave not yet been evaluated by experts. They used an algorithm to measure the noise and qubit errors.
Quantum computers can perform multiple calculations at the same time thanks to the laws of quantum mechanics and entanglement, unlike classical computers that perform them one by one. The more qubits there are, the more powerful the machine is, capable of performing complex calculations in a matter of seconds, where a superordinateur classical would take thousands of years.
To achieve “quantum supremacy,” computers with millions of qubits would be needed. Currently, the largest machines have regarding 1,000. Because qubits are prone to errors, researchers focus on their reliability rather than their number.
Quantinuum’s H2-1 was tested with the XEB benchmark, achieving a score of 0.35, an unprecedented result. In comparison, Quantinuum’s Sycamore computer Google had achieved a score of 0.002 in 2019. This means that the H2-1 can produce error-free results 35% of the time.
Achieving “quantum supremacy” would require quantum computers with millions of qubits.

Ilyas Khan, Product Director at Quantinuum, said their goal is to create universal and reliable quantum computers. The results of this research show that the benefits of reliable quantum computers might be achieved sooner than expected, marking a promising advancement in this field.
