Deterministic and Storable Single-Photon Source Based on a Quantum Memory
Deterministic and Storable Single-Photon Source Based on a Quantum Memory
A single photon source is realized with a cold atomic ensemble ($^{87}$Rb atoms). In the experiment, single photons, which is initially stored in an atomic quantum memory generated by Raman scattering of a laser pulse, can be emitted deterministically at a time-delay in control. It is shown that production rate …
