摘要
提供了一种计算多光子相干态高阶压缩的简便方法，并对八光子相干态的高阶压缩特性进行了详细的研究，还提出了一些多光子相干态高阶压缩的普遍性质．
A simple method to calculate higher order squeezing of multiphoton coherent states of quantum radiation field is provided.Concretely,higher order squeezing properties of eight photon coherent states are investigated in detail.It is indicated that eight photon choerent states do not exhibit the second,fourth,and sixth order squeezing,but for these quantum states there simultaneously exist eighth even more higher order squeezing with respect to both quadrature components.
