Raw Photon Coincidence Counts with Timestamps from Three APDs

4.0 GB of raw timestamp data for photon events recorded by three avalanche photodiodes (APDs). The dataset, authored by Xia Binke and last updated in April 2026, includes coincidence counts between projected signal photons and herald photons.

Use Cases

• Calibrating quantum state detection systems based on photon coincidence counts.
• Modeling and verifying photon correlation statistics from the described APD setup.
• Testing quantum key distribution protocols using the herald and signal photon data.
• Analyzing temporal jitter and detection efficiency in multi-APD experimental configurations.

Strengths

• Raw data format preserves original experimental timestamps for detailed analysis.
• Data size is 4.0 GB, indicating a substantial volume of photon event records.
• Released under a permissive CC-BY-4.0 license for broad reuse.

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.
