摘要: 本文运用IWOP技术推导出Wigner算符的相干态显式,计算出一类特殊单模压缩态z〉f,g=exp-z22+(fz+gz*)a+-fga+[]20〉的Wigner函数解析式,通过数值计算可以看到,参数f和g的任一个取值固定时,另一个参数的旋转取值会使得特殊单模压缩态的Wigner函数表现出旋转平移特性.Abstract: In this paper, the expression of Wigner operator in the coherent state is derived using the IWOP technology. The Wigner function of a kind of special single-mode squeezed state is calculated. When the rotation parameter value changes, the numerical calculations show that the Wigner function in the phase space possesses a rotation displacement feature.
