    "abstract": "A single photon source is realized with a cold atomic ensemble ($^{87}$Rb\natoms). In the experiment, single photons, which is initially stored in an\natomic quantum memory generated by Raman scattering of a laser pulse, can be\nemitted deterministically at a time-delay in control. It is shown that\nproduction rate of single photons can be enhanced by a feedback circuit\nconsiderably while the single-photon quality is conserved. Thus our present\nsingle-photon source is well suitable for future large-scale realization of\nquantum communication and linear optical quantum computation.",
