Quantinuum achieved a new quantum error-correction record with 99.9995% logical fidelity on its Helios system, reducing errors tenfold and validating its path to a universal fault-tolerant quantum computer by 2029.
This Wire brief sits within Fusion42's coverage of Quantum Computing, and 4 sources have reported it between 19 Oct 2026 and 27 Oct 2026.
◆ ◆ The Wire takeaway
Quantum computing founders can now back designs that slash error rates tenfold using trapped-ion tech, opening a clearer path to scalable, fault-tolerant machines by 2029. You must choose or develop error-correction codes that fit your hardware trade-offs and position for commercial quantum workloads early.
