我们研究了压缩偶相干态和压缩奇相干态的非经典统计性质，这是由两个位移参数相位差为π的压缩相干态的叠加态所定义的。我们证明了压缩均匀相干态下的场与输入压缩相干态相比，可以表现出显著增强的压缩能级和平均光子数。我们也给出了导致这种叠加的物理过程的例子。
We examine the nonclassical statistical properties of the squeezed even and the squeezed odd coherent states defined by the superposed states involving two squeezed coherent states with phase difference π between their displacement parameters. We demonstrate that the fields in the squeezed even coherent state can exhibit a remarkably enhanced squeezing level and mean photon number in comparison with the input squeezed coherent state. We also give examples of physical processes that lead to such a superposition.
