Quantinuum has announced that its H-Series processor has surpassed the ability to be simulated by the world’s best supercomputers, enabling the company to “extend the lead in the race towards fault tolerant quantum computing.”

The UK quantum computing company has announced a major qubit (or quantum bit) count enhancement to its flagship System Model H2 quantum computer from 32 to 56 trapped-ion qubits.

Formed in 2021 by Honeywell and Cambridge Quantum, Quantinuum has to date raised approximately $625m to further the development and commercialisation of quantum computing. Its mission is to see the quantum computing industry depart the era when quantum computers could be simulated by a classical computer.

This has been achieved, with the announcement that its upgraded H2-1 from 32 to 56 qubits makes its processor impossible to classically simulate.

This upgrade is also challenging the world’s most powerful supercomputers. It proved this in a demonstration in partnership with US finance company...
