Quantinuum Breaks Error-Correction World Record by 10x, Validating Its Leading Path to Fault-Tolerant Quantum Computing by 2029
Quantinuum achieved a world-record 99.9995% logical fidelity on its Helios commercial quantum computer, equivalent to just five errors per million operations. The error rate is 10x lower than the company's own September 2026 record and 100x lower than the best published result from any other hardware modality, reported by Google Quantum AI on a superconducting system.
