连续变量量子态的光学操控

Optical Manipulations of Quantum States with Continuous Variables

量子态的光学操控是指在光场的传输、存储和频率变换等过程中用光学方法对光场的量子态进行操作与控制。量子态操控是量子通讯及量子态制备和应用的基础。在简要介绍连续变量多组份纠缠态光场制备的基础上,概述基于多组份纠缠态光场的连续变量量子通讯网络及在执行压缩态和纠缠态光场操控方面的实验研究进展。

The optical manipulation of quantum states means to manipulate and control the quantum states of light in the processes of its transmission,storage,frequency-conversion and so on,based on optical schemes.The manipulation of quantum states is the important research subject in quantum information science.We briefly introduce the progress of the experimental investigation on the preparation of multipartite entangled states of optical field,quantum communication network as well as the optical manipulation of squeezed and entangled states of light.
