| 摘 要： | 研究了由两个任意相干态构成的叠加态｜ψ〉=a｜β〉+beiφ｜mβeiδ 〉的量子统计性质，结果表明此种叠加态普遍存在着压缩效应或光子反群聚效应.叠 加态的量子效应依赖于β2和振幅系数m，同时改变相干态间的位相差δ和叠加 系数间的位相差φ也将对叠加态的压缩效应或反群聚效应起着重要的作用.关键词：相干态叠加态压缩效应反群聚效应

| Abstract: | In this paper, the quantum statistical properties of the superposition state,a｜ β〉+beiφ｜mβeiδ〉,which involves two arbitrary coh erent states, are investigated. The results show that this kind of super-positio n states generally exhibits squeezing effect or anti-bunching effect. The quantu m effects of the superposed state depend on β2 and the amplitude coe fficient m, as well as the changes of the phase difference between two coherent states δ, and the phase difference between two superposition coefficients φ al so plays an important role in squeezing or anti-bunching effects. |
