摘　　要：将双模纠缠相干光场中一束光场与腔中单个二能级原子发生非共振k光子相互作用,经腔QED演化之后,对原子作选择性测量,通过调节相互作用时间、跃迁光子数和失谐量,实现控制腔外光场量子统计特性的目的.经过比较分析发现相比于单光子过程和非简并多光子过程光场的反聚束和压缩效应变化更加明显.Considering two-mode entangled coherent light fields, one mode of the fields is poured into the cavity and interacts with a two-level atom by k photons non-resonantly. After the evolution of Cavity-QED, we have a selective measurement to the atom. Through operating the evolution time, the number of transition photon and detune, we can control the quantum statistical property of the light fields outside of the cavity. After comparative analysis, it is found that, comparing with single photon process and the multiple-photon process, the diversification of anti-bunching and squeezing of the light fields is better.
