摘　　要：基于量子力学基本理论,构造了一个由相干态与单模压缩态构成的新迭加态:|φ>=N(|α>+eiφ|β>g);详细讨论了其压缩效应和光子数反聚束效应,发现该迭加态呈现出多样的量子特性。在按类似奇偶相干态的方式迭加时,迭加态具有奇偶相干态和压缩奇偶相干态的某些特性。作为特例,当压缩因子为0时,可以得到奇偶相干态和相干态。Based on the quantum superposition principle, we construct a new type of superposition composed of coherent state and squeezed state ｜φ〉=N（1α〉＋eiφ｜β〉g） ; and study its squeezing effect and photon anti-bunching effect. The results show that this kind of superposition exhibits fluent quantum properties. When superposed as even/odd coherent states, the superposition exhibits some properties of both even/odd coherent states and squeezed even/odd coherent states. The even/odd coherent and coherent state can be obtained as a special case when the squeezed factor r is zero.
