标题： Feasibility of single-photon cross-phase modulation using metastable xenon in a high finesse cavity

摘要： 在单光子水平上的交叉相位调制在量子光学中有广泛的基本应用，包括宏观纠缠态的生成。 在这里，我们描述了一种实用的方法，使用高精细度腔中的亚稳态氙气在单光子水平上产生弱交叉相位调制。 我们估计了可实现的相位偏移，并简要更新了其实现的实验进展。 通过一个简单的微扰理论计算和一个数值矩阵对角化方法，预测了大约20毫弧度的单光子交叉相位调制。 显示英文摘要

摘要： Cross-phase modulation at the single-photon level has a wide variety of fundamental applications in quantum optics including the generation of macroscopic entangled states. Here we describe a practical method for producing a weak cross-phase modulation at the single-photon level using metastable xenon in a high finesse cavity. We estimate the achievable phase shift and give a brief update on the experimental progress towards its realization. A single-photon cross-phase modulation of approximately 20 milliradians is predicted by both a straightforward perturbation theory calculation and a numerical matrix diagonalization method.
