摘要
从四能级暗态极化子出发,讨论双模量子场与原子介质的信息转换过程以及2信号场之间的信息转换过程。利用双-Λ型四能级原子系统,可以存储双模量子态(包括一些纠缠态),从理论上解释了双模量子信息在介质中的"写入"和"读出"过程。提供了双信号场存储的实验方案。
According to the double-Λ dark-state polarons,quantum information can be exchanged not only between the two-signal fields and the collective atoms,but also between the two signal fields.Some two-mode quantum states,including some entangled states,can be stored in the double-Λ atomic process,thus quantum information of the two-signal field can be written and read in the medium.Furthermore,an experimental scheme for storing the two-mode quantum states is given.
