| 摘 要： | 通过数值计算研究了增加光子奇q相干态aq+m|α>qo和增加光子偶q相干态aq+m|α>qe的高阶压缩效应.结果表明:当q较小时,态aq+m|α>qo和aq+m|α>qe都能呈现出强烈的奇次方阶压缩效应,但无偶次方阶压缩效应,而且奇次方阶压缩随m的增大而增强.当m=0时aq+m|α>qo和aq+m|α>qe为光场振幅偶次幂的最小测不准态,但当m≠0时它们不是光场振幅偶次幂的最小测不准态.

| Abstract: | The higher power squeezing effects of the photon-added even and odd q-coherent states (aq+m|α>qe and aq+m|α>qo) is numerically studied.It is shown that for small q,the state aq+m|α>qe and state aq+m|α>qo can exhibit strong odd power squeezing effect but no even power squeezing effect.As m increases,the odd power squeezing increases.The photon-added even and odd q-coherent states are the even power minimum uncertainty states for m=0,but they are not for m≠0. |
