在由三个经典控制场驱动的五能级三重以型原子系综与三个多模量子先场相互作用的系统中,得到了该系统的极化子.利用求得的极化子结果研究了光量子态存储到原子激发态,或从原子系综中释放出光量子信息.在释放过程中,通过绝热调节控制场的Rabi频率,能得到纠缠光子态.尤其是在一定条件下,能利用该系统能制备一类W态,这类态在量子信息处理中有潜在的应用.

We derive the polariton picture in the interaction of three multi-mode quantized fields with a five-level triple-Aatomic ensemble driven by three classical control fields.The storage(or retrieval)ofthe quantum state of light in(or from)the atomic polarization state is investigated:several entangled Fock states of light can be created in the process of retrieving photon state from atomic ensemble by modulating the control fields.Particularly,this system can be used to generate a class of W states,which have a potential application in quantum information processing.
