摘要
本文利用Pegg定义的位相,研究了弱压缩真空态的位相特性。分析了光学衰减器中位相演化规律,并将位相几率分布中的扩散与Fokker—Planck得出的结果进行比较。
In this paper, the phase property of weakly squeezed vacuum state is studied using the dejinition of the phase by Pegg. We use the phase states to analyze phase evolution in optical attenuater. The resulting diffusion of the phase probability distribution is compared with that obtained in conventional Fokker-Planck treatments
