Room-Temperature Deterministic Single-Photon Sources

Light sources that emit exactly one photon at a time, on demand, operating at room temperature rather than requiring cryogenic cooling -- a key enabling component for quantum communication, quantum sensing, and photonic quantum computing, serving all three as an upstream component rather than belonging to any one of them. Anchored at Lounis & Moerner, "Single photons on demand from a single molecule at room temperature" (Nature 407:491-493, 2000) -- the actual first demonstration of a triggered, room-temperature single-photon source (a single organic molecule in a solid), corrected from an earlier draft that anchored on Tran et al.'s 2016 hexagonal-boron-nitride result (Nature Nanotechnology 11:37-41) found during 2026-08-28 noise-testing to be a later, specific-material advance within an already 16-year-old field, not its origin -- real intermediate landmarks exist too (e.g. Beveratos et al. 2002, NV-diamond). Verified independently distinct from Photonic Quantum Computing via live co-citation check (0.7% overlap, 2026-08-28 Distinctness Test pass).
