| 摘 要： | 研究了压缩相干态的振幅平方压缩特性,发现压缩相干态也存在这类压缩,但存在的条件与通常压缩不同,特别是压缩真空态,在通常压缩最大的方向上振幅平方压缩却不存在,反之亦然.从这个角度证明了振幅平方压缩并不与通常意义下的压缩等价.

| Abstract: | The characteristic of amplitude-squared squeezing of squeezed coherent
state is studied.It is found that this kind of squeezing also exists in
squeezed coherent state,but the existing condition is different from that of
usual squeezing.And,in particular,the amplitude-squared squcezing doesn't
exist,in the direction of maximum usual squeezing for squeezed vacuum state
and vice-versa.From this point of the view,it is proved then that the ampli-
tude-squared squeezing and usual squeezing are nonequivalent. |
