THE PERFORMANCE LAYER FOR QUANTUM ERROR CORRECTION

QubitBoost lowers your logical error rate without replacing the decoder. Decoding performance is in private pilot. Around it sits a hardware-validated platform you can run today that improves runtime efficiency and result assurance.

Every number on this page traces to a hardware experiment directory. Every claim is reproducible. No synthetic benchmarks, no cherry-picked baselines.

DECODING PERFORMANCE

lower logical error rate, any decoder

DECODER ADAPTOR

private pilot

The decoder you already run reports a lower logical error rate. No decoder swap, no retraining, with a built-in guard so it is never made worse.
