依赖于强度耦合的多光子相互作用过程的纠缠交换

Entanglement Reciprocation in the Process of Multi-Photon Interaction by the Intensity-Dependent Coupling

利用全量子理论,建立了由多个"原子-腔场相互作用"构成的联合物理模型,研究了依赖于强度耦合的多光子相互作用过程,结果表明:如果适当控制原子穿越腔场的速度,就可实现量子纠缠信息在原子与腔场之间的交换传递,而且在某些条件下,信息能够完全转换,另外,利用计算纠缠度的方法所得结果与其完全一致。

Using of complete quantum theory,an united physical model which consist of the multi-atom and multi-cavity field is proposed.In this system,the procedure of multi-photon interaction by the intensity-dependent coupling is studied in detail.It is found that the quantum entangled information can be reciprocated between atoms and cavity fields if atoms cross the cavities with a controlled speed.The information can be completely transmitted under some conditions.Besides,the results of calculation entanglement degree are entirely same with above mentioned.
