Willow Surface-Code Detection Events from Google's Quantum Experiments

Willow Surface-Code Detection Events contains detection events and logical-observable flips derived from Google's below-threshold surface-code dataset. The data is ingested from a Zenodo source and represents experimental shots for rotated surface codes at distances 3, 5, and 7 in X and Z memory. Author ShayManor uploaded the dataset to Hugging Face, with a last recorded update on 2026-06-19.

Use Cases

• Benchmarking quantum error correction decoders based on detection event patterns.
• Analyzing logical error rates for rotated surface codes at different distances.
• Validating Stim's measurement-to-detector converter outputs against raw experimental data.
• Studying the correlation between sweep bits and detection events in quantum memory experiments.

Strengths

• Data is derived from Google's experimental quantum hardware, providing a real-world benchmark.
• Detection events are generated using Stim's measurement-to-detector converter, a standard tool in the field.
• Covers rotated surface codes at multiple distances (3, 5, 7) for X and Z memory.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
