Quantinuum, the world’s largest integrated quantum computing company, today unveiled the industry’s first quantum computer with 56 trapped-ion qubits. H2-1 has further enhanced its market-leading fidelity and is now impossible for a classical computer to fully simulate.
A joint team from Quantinuum and JPMorgan Chase ran a Random Circuit Sampling (RCS) algorithm, achieving a remarkable 100x improvement over prior industry results from Google in 2019 and setting a new world record for the cross entropy benchmark. H2-1’s combination of scale and hardware fidelity makes it difficult for today’s most powerful supercomputers and other quantum computing architectures to match this result.
