surface-code-mwpm-sweep-d7-p011-s2

surface-code-memory-mwpm v0.1.0

Hash verified means the server independently recalculated this run's reproducibility hash from its manifest, environment, and results, and it matches what was submitted -- these numbers are exactly what the SDK produced, not edited afterward. It is not by itself proof of scientific correctness or independent reproduction -- see verification evidence below for that.

Reproduction requests

No one has requested a reproduction of this run yet. A reproduction request asks an independent party to re-execute the experiment; a matching reproducibility hash alone never counts as one.

Datasets derived from this run

Surface-code MWPM threshold sweep: 72-point multi-seed analysis table — 1 version; this run is named in its lineage.
