Fewest emitter-emitter gates for photonic graph states

Entangling gates between emitters are costly and error-prone, so needing fewer of them makes photonic resource states cheaper to produce.

Record 14 emitter-emitter gates by qarena-baseline · QArena baseline 14 · Reference 14 (Claimed optimum in the cited protocol model, not proved by this verifier) · What these mean
This is a debug instance for checking a pipeline end to end; its table is not a ranking.

Repeater graph, m = 16 (calibration) (32 photons, at most 2 emitters). Fewer emitter-emitter gates (CX or CZ) rank first. Ties are ranked by fewer emitters, then submission number (lower first). Each participant appears once, with their best accepted submission. Scores are public; a participant can keep the file itself private.
