05:47 AM EDT, 10/21/2025 (MT Newswires) -- IonQ ( IONQ ) said Tuesday it has achieved the world's highest two-qubit gate performance, with fidelity surpassing 99.99%.
The previous world record of 99.97% was set last year by Oxford Ionics, which is now part of IonQ ( IONQ ).
"This is a pivotal moment for the quantum computing industry, as we have now hit world-record quantum computing performance on mass-manufacturable technology," Chris Ballance, co-founder of Oxford Ionics, said. "In exceeding the 99.99% threshold on chips built in standard semiconductor fabs, we are now on a clear path to millions of qubits whilst unlocking powerful new commercial applications sooner."
Two-qubit gate fidelity is a key performance metric in quantum computing, measuring how accurately quantum operations are performed.
IonQ ( IONQ ) shares were up 3.2% in recent premarket activity.
