Quantinuum reports 99.914% two-qubit gate fidelity on H1-1
Apr 16, 2024
Quantinuum reports 99.914(3)% two-qubit gate fidelity on its commercially available H1-1 trapped-ion computer. Its randomized benchmarking data cover all five gate zones, with each zone above 99.9% within the reported uncertainties.
Why it matters
Low errors across a working processor's gate zones matter for running error correction consistently, beyond the performance of a single laboratory gate.
