摘要
基于三阶非线性光学效应———简并四波混频 ,提出了一种新的制备明亮的纠缠光子源的方案 ,从理论上证明了相位共轭光和透射的信号光是处于量子纠缠的 .
We present a new scheme to generate bright entangled states of light based on degenerate fourwave mixing in a χ (3) medium. Under certain conditions, the phase conjugated wave and transmitted signal wave can be quantum entangled.
