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 (five errors per million operations) on its Helios commercial quantum computer, breaking its own September 2026 record by 10x and the best published result from other modalities by 100x. The result was obtained using a 'color code' on the same Helios hardware that ran September's Helix-code demonstration, showing the flexibility of its error-correction architecture and trapped-ion technology.
