应用Pegg和Barnett提出的相位算符和相位态理论,研究了激发压缩真空态的相位概率分布特性.数值计算结果表明,激发压缩真空态的相位概率分布主要受到相位参量和压缩参量的调节,相位参量使相位概率分布呈峰值结构,压缩参量的变化将影响相位概率分布的峰值强度,此外激发光子数对相位概率分布也有较大的影响. Based on the phase operator and phase theory proposed by Pegg and Barnett, the phase probability distribution of the excited vacuum state is studied. The numerical results show that the phase probability distribution of the excited vacuum state is mainly controlled by the phase and compression parameters. The phase The parameters make the phase probability distribution have a peak structure, and the change of the compression parameters will affect the peak intensity of the phase probability distribution. In addition, the excitation photon number also has a great influence on the phase probability distribution.
