| 摘 要： | 本文构造了一种单模单参数q光场叠加态|Ψ>q=c(|α>q+β|0>q),利用Zhang等人提出的单模辐射场的振幅M次方压缩的定义对态|Ψ>q的压缩及高阶压缩特性进行了详细的研究.结果发现,在一定的条件下,态|Ψ>q可存在任意的M次方压缩效应. 最后,通过数值计算还详细研究了态|Ψ>q的压缩和平方压缩性质.

| Abstract: | In this paper,the superposition state of single-mode and single-parameter q-light field|Ψ>q=c(|α> q+β|0> q) is constructed,and its squeezing and higher-order squeezing properties are studied in detail making use of the definition of amplitude M-order squeezing of single-mode electromagnetic-field put forward by Zhang et al.The results show that any M-order squeezing effect of this state |Ψ>q can exist.Its squeezing and squared squeezing properties are studied with the aid of numerical calculation. |

| Keywords: | Superposition state of single mode and single parameter q light field Squeezing Higher order squeezing Squeezing parameter |
