摘　　要：　通过与理想压缩态的比较,发现双光子相干态的光子数平均值不仅与正交相振幅的量子涨落有关,还与初始的相干态有关.本文还对其相应的物理意义进行了详细地分析.We investigate the average number of photons in the two-photon coherent state by comparison with the ideal squeezed state and find that it relates to the quantum fluctuation of the quadrature and the phase of the initial coherent state. The physical significance of the relations is analyzed in detail.
