摘要
根据Zhang等人提出的高阶压缩,研究了奇偶相干态的高阶压缩性质,发现偶相干态可存在奇数阶压缩,而奇相干态不存在任何阶压缩。最后讨论了这种高阶压缩效应的独立性。
According to the definition of higher--order squeezing given by Zhang et al.,the properties of the higher--order squeezing of even and odd coherent states arestudied in this paper. It is found that even coherent state may have Nth--ordersqueezing for odd N, and the odd coherent state does not have any order sque-ezing. Finally, the independence of this kind of higher--order squeezing effectfrom the others is discussed.
