摘　　要：研究两纠缠原子之一在光腔中与两个非简并双光子的相互作用,通过针对性选择测量,使得系统场被约化为不同的态矢,得到纠缠交换的目的;分析原子的纠缠度对约化后光场性质的影响,结果表明纠缠度强烈影响光场的平均光子数分布和二阶量子相干性.The paper mainly considers the interaction about one of the two entangled atoms with the nondegenerate two-photon in cavity. After selective detection on one of the atoms, the properties of the light field has been investigated. It is proved that the average photon numbers and the second-order quantum coherence are dramatically influenced by the entangled degree of the atoms.

关 键 词：纠缠度 纠缠交换 平均光子数 二阶量子相干性
