摘　　要：1981年,Caves教授首次提出“压缩态”的概念,并指出利用压缩态光场可以提高激光干涉引力波探测的灵敏度。在过去的四十年,压缩态光场不仅成功用于突破标准量子极限的引力波探测、位移测量、位相测量等量子精密测量领域,而且基于单模压缩态制备的双模压缩态和多组份纠缠态也在量子计算、量子通信等量子信息处理中扮演着重要的作用。本文简要介绍了压缩态光场的基本概念、制备、探测方法及其在量子精密测量、量子通信、量子计算中的应用进展。In 1981,Professor Caves first proposed the concept of“squeezed state”and indicated that the sensitivity of laser interference gravitational wave detection can be improved using the squeezed states of a light field.For the past forty years,the squeezed states of light have been successfully used in quantum precision measurements such as gravitational wave detection,displacement measurement,and phase measurement that beat the standard quantum limit.Twomode squeezed and multiparty entangled states prepared based on singlemode squeezed states also play an important role in quantum information processing,such as quantum computation and quantum communication.This review briefly introduces the basic concepts,preparation,and detection methods of the squeezed states of light and their application progress in quantum precision measurement,quantum communication,and quantum computing.
