摘要:

用冷原子系综($^{87}$ Rb原子)实现单光子源。在实验中,最初存储在由激光脉冲的拉曼散射产生的原子量子存储器中的单光子可以在受控的时间延迟下确定性地发射。结果表明,在保持单光子质量不变的情况下,反馈电路可以显著提高单光子的产生率。因此,我们目前的单光子源是非常适合于未来大规模实现量子通信和线性光量子计算。

英文摘要:

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 of single photons can be enhanced by a feedback circuit considerably while the single-photon quality is conserved. Thus our present single-photon source is well suitable for future large-scale realization of quantum communication and linear optical quantum computation.
