QEC decoder accuracy on fixed circuit-level memory experiments
A decoder decides whether error correction works on real circuits. Fixed shots with hidden labels let decoders be compared on identical circuit-level data.
Instance: Code and noise model
Record 4,249 logical errors by qarena-baseline · QArena baseline 4,249 · Reference – (No reference score: published rates come from other shots) · What these mean
BB [[72,12,6]], p = 0.003 (200,000 shots with private labels; X and Z memory, 6 cycles, 504 detectors, 12 observables). Fewer logical errors over the 200,000 ranked shots ranks first; a shot counts once however many of its observables are wrong. Ties are ranked by submission number (lower first). Batch times are shown but never ranked. Each participant appears once, with their best accepted submission. Scores are public; every prediction file stays private (see Rules).
