辐射场的压缩的混沌态——Ⅰ. 特征函数和压缩性质

Ⅰ. Characteristic function and squeezing

本文用Wigner特征函数方法将压缩的概念推广到一般量子态;详细讨论了一类新的光场状态——压缩的混沌态的量子统计性质,并提出辐射场与其共轭场的光子配组的概念作为其压缩性质的物理解释.

The concept of squeezing has been generatized to any quantum states of the rediation field using wigner characteristic function method. As and example, we have discussed the squeezing of the light field in a new quantum state, squeezed chaotio state. Physically the squeezing can be explained to be created by proton-mixing between the light and its phase conjugate field.
