摘　　要：研究了压缩相干态和真空态构成的相干叠加态的振幅平方压缩特性和量子统计性质.结果表明,在一定条件下,相干叠加态在场的两个正交分量上分别产生振幅平方压缩效应,并呈现光子聚束及超泊松分布等特性.相干叠加态的压缩效应与压缩参量及相干参数有关,相干态的相位和压缩相位也会对叠加态的非经典效应产生影响.In this paper, the squeezing effect and quantum statistical properties of one new coherent superposition state were investigated. The results showed that the coherent superposition state brings squeezing effect,bunching effect and super-poisson distribution. The effects of the coherent superposition state depend on the changes of squeezing coefficient and coherent coefficient, as well as that of coherent state phase and squeezing phase.
