摘要
光场压缩态是一种非经典光场 ,它在超标准量子极限 (SQL)的高精度光学测量、超低噪声光通信及量子通信等领域有着广泛应用前景 ,是物理学和信息科学交叉前沿研究课题 .文章介绍了光场压缩态的产生及它在亚散粒噪声光学测量 (sub shot noise limitopticalmeasurement)和量子信息中的重要应用 .
Squeezed state light is a nonclassical optical field which has extensive potential applications in optical measurement with high sensitivity exceeding the standard quantum limit as well as in optical communications and quantum information with extremely low noise. This has given birth to cross-disciplines of physics and information science. An overview is presented of the generation of squeezed state light fields and their important applications in sub-shot-noise-limit optical measurement and quantum information research.
