| 摘 要： | 通过数值计算,研究了增加光子对相干态|,ξq;m〉A=a m|,ξq〉和减少光子对相干态|,ξq;-m〉S=bm|,ξq〉的等阶Y压缩效应.结果表明:对于增加光子对相干态a m|,ξq〉和减少光子对相干态bm|,ξq〉,光场都存在着等阶K(=2,3,4,5…)次方Y压缩效应,但是增加a模的光子或取走b模的光子,即随着场模上光子增加(减少)数m的增大,二者的等阶K次方Y压缩效应均减弱,且有相似的曲线变化规律.

| Abstract: | The equal-order Y-squeezing effects of photon-added pair coherent state and photon-subtracted pair coherent state are studied numerically.It is shown that the photon field can exhibit the equal-order K-th power Y-squeezing effects,but when photons are added to mode a of a pair coherent state or subtracted from mode b of a pair coherent state,i.e.as the number of photon pair m increases,the equal-order K-th power Y-squeezing effects of these two states both decrease with the similar trend. |
