Team simulates quantum error correction to below 1 in 10 billion
A team has simulated quantum error-correcting circuits and computed logical failure rates below 1 in 10 billion. The result reaches beyond the scale where such simulations can typically resolve rare logical errors.

Within two years, this simulation approach could let researchers benchmark candidate surface-code configurations at logical failure rates low enough to inform fault-tolerant architecture choices before hardware reaches that performance.
The work appears to overcome rare-event sampling limits that have made sub-1e-9 logical error estimation expensive. If the method transfers to other noise models and code families, groups could use it to test decoder and code-distance trade-offs earlier in the design cycle.
