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)
