连续变量量子信息是量子信息科学研究的一个重要内容。基于光学模的连续变量量子信息处理,以光场量子态为量子资源,结合各种量子操控手段,完成信息的传输和处理。本文简要介绍用于连续变量量子信息处理的光量子态的概念、制备方法和操控手段,以及连续变量量子通信、量子计算和量子纠错方面的研究进展和发展趋势。
Quantum information processing with continuous variables is an important part in quantum information science. Quantum information processing with continuous variables based on quantum state of optical field complete the transmission and processing of information by using quantum state of optical field as quantum resource and combining all methods of quantum manipulation for optical eld. In this short review, we briey introduce the concept, preparation and manipulation methods for optical quantum state which plays important roles for quantum information processing with continuous variables. The research progress and development tendency in quantum communication, quantum computation and quantum error correction with continuous variables are also presented.
