|
| PERO cryogenic laser SPDC entanglement experiments — raw footage, analysis |
| plots, and the canonical experiment record, split 80/10/10 (train/val/test). |
|
|
| ## Contents |
|
|
| - `data/split/train.jsonl` · `val.jsonl` · `test.jsonl` — record splits |
| - `metadata.json` — experiment metadata (temperatures, wavelengths, crystals, |
| measured fidelity/efficiency/coherence) |
| - `split_manifest.json` — record → split mapping |
| - `data/raw/` — analysis plot images (small media) |
|
|
| ## Records (12 total) |
|
|
| - 6 experiment video runs (cryo-laser-array, raw footage) — linked from the |
| GitHub source repo (large media stays on GitHub, per the split-repo plan) |
| - 5 analysis plot images (included in `data/raw/`) |
| - 1 canonical freezer-laser experiment summary (PDF-spec parameters: |
| T = -18…-25 °C, λ = 450/532/633 nm, BBO/KTP/LiNbO₃, F = 0.999423, |
| 847 pairs, 67.3 % splitting efficiency, 81.7 % spatial coherence) |
