对于两种形式的纠缠相干态,通过M.Hillery提出的"双模和压缩"和"双模差压缩"研究了其的压缩特性,并与R.Loudon提出的双模压缩算符计算其压缩特性结果进行比较.发现第一种形式的纠缠相干态的压缩特性相同,但第二种不同.
For two kinds of entangled coherent states,we calculate their squeezed property by Sum and difference squeezing which proposed by M.Hillery and by double model squeezing operator which proposed by Loudon.R,two results are compared.And we find for the first entangled coherent states the result is same,but the second is not.
