Quantinuum has set a new world record by reducing logical errors tenfold on its Helios trapped-ion system, achieving 99.9995% fidelity through an integrated architecture that combines color codes with tailored AI decoders. This exponential suppression of errors as code distance increases suggests a viable path toward universal fault tolerance using fewer qubits than other modalities currently require. The breakthrough validates the scalability of trapped-ion technology and its hybrid hardware-software approach for practical quantum computation.

Quantinuum Says it cuts quantum errors by 10x, a new world record

Quantum ZeitgeistOctober 19, 20263 min read

Quantinuum breaks its own error-correction record by 10x, achieving 99.9995% logical fidelity on the Helios computer.

Quantinuum reports achieving 99.9995% logical fidelity on its Helios computer, a new world record representing just five errors in a million quantum operations. This result surpasses the company’s own record from September 2026 and is 100 times lower than the best published result from Google Quantum AI using a superconducting system, Quantinuum says. Dr.…
