Willow Surface-Code Detection Events (ingested)
Detection events and logical-observable flips derived from Google's Willow below-threshold surface-code dataset (Zenodo 10.5281/zenodo.13273331), rotated surface code at distances 3, 5, 7 in X and Z memory.
Each row is one experimental shot. Detection events are derived from the raw
device measurement records with Stim's measurement-to-detector converter, using
the per-shot sweep bits, and validated to reproduce the dataset's shipped
detection_events.b8 / obs_flips_actual.b8 byte-for-byte for all
420 configurations.
Columns
| column | type | meaning |
|---|---|---|
distance |
int16 | code distance d (3, 5, 7) |
basis |
string | X or Z memory |
rounds |
int16 | number of QEC cycles |
orientation |
string | patch location label on the chip (e.g. q4_5) |
shot |
int32 | shot index within the configuration |
detectors |
list<bool> | which detectors fired (length num_detectors, = 2 * rounds * (d^2-1)/2) |
observable |
bool | ground-truth logical flip the decoder must predict |
One Parquet shard per (distance, orientation, basis, rounds) configuration under
data/. The decoder sees only detectors; observable is the held-out answer key.
