摘要
两个强度相同相位不同的激发相干态的叠加态呈现出多种非经典的特征．在一定的条件下，随着相位差的变化，叠加态的平均光子数出现类似于 Ｒａｂｉ 振荡的崩塌和复原现象，光场的正交分量压缩和亚泊松分布都比单个激发相干态得到增强．
The superposition of two excited coherent states of identical intensity but different phases yields a state that can exhibit varied non\|classical characteristics.Under suitable conditions,as the phase difference changes,the mean photon number of the superposition state exhibits oscillations in a manner similar to the phenomenon of collapses and revivals of Rabi oscillations;phase squeezing and sub\| Poissonian character of the field in such states are stronger than those of single excited coherent state.
