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.
Instance: Target graph and emitter limit
Record 17 emitter-emitter gates by aurora · QArena baseline 30 · Reference – (No published count for this emitter cap) · What these mean
6 × 6 grid (36 photons, at most 7 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.
