摘要

从理论上提出了一种制备窄线宽三光子频率纠缠态的实验方案，该三光子纠缠态利用在两个冷原子系综中的四波混频和电磁诱导透明来产生. 利用二阶微扰理论完成了相关计算，并通过分析光子符合计数，研究了该三光子纠缠态的特性，证明其具有类似于离散变量三粒子W态的基本性质，并具有光子反群聚效应.

We propose a scheme for the generation of narrowband triphoton frequency-entangled states. This scheme uses the four-wave mixing and the electromagnetically induced transparency in two cold-atom ensembles. By using the second-order perturbation theory, some relevant calculations are performed. By analyzing the coincidence-counting rate, we study the correlation and nonclassical properties of these states, and find that they have a similar feature to that of the discrete-variable W state, and can show the antibunching effect.
