Abstract

This paper demonstrates a room-temperature single-photon source with a near-millisecond built-in memory, significantly exceeding previous room-temperature systems. A single photon is retrieved from the memory after a variable storage time following heralded loading. The single-photon nature is validated by strong suppression of the two-photon component, and non-classical correlations are maintained for up to 0.68 ms.
