摘要
利用Ｂａｒｎｅｔｔ和Ｐｅｇｇ提出的测量相位算符讨论了奇偶相干态中的相位涨落及其高阶涨落。在测不准关系和高阶测不准关系基础上给出了测量相位压缩和高阶压缩的二类定义，并用这二类定义研究了奇偶相干态中测量相位的二阶和高阶压缩情况。
The phase fluctuations and higher order fluctuations in odd and even coherent states have been discussed via the measured phase operators introduced by S. M. Barnett and D. T. Pegg. Based on the uncertainty relation and higher order uncertainty relation, two kinds of definitions of squeezing and higher order squeezing for the measured phase operators are introduced. Using these definitions, the squeezing and higher order squeezing of measured phase operators in odd and even coherent states have been studied.
