摘要
本文研究了ｑ玻色湮没算符平方的本征态的压缩性质。得到了其相位振幅和相位振幅平方的正序排列方差的解析表达式并讨论了压缩区域与ｑ参数及位移参数的关系。
We present a study on the compression properties of the eigemstates of a. The analytical expressions of the normal-ordered variance of both phase-amplitude oferators and square of phase-amplitude operators are obtained and the relations betweem compression regions and q parameter and displacement parameter are ciscussed.
