论文摘要
我们提出了一种在随机时间对封闭量子系统上的干涉测量测量中处理数据的方法。为此，引入了时间相关矩阵，使我们能够提取量子系统的动态属性。定义了广义期望值后，我们获得了时间尺度的分布，平均过渡时间和相关时间。存在与量子波动分开的经典极限。后者的特征是与普遍期望值的极点相关的共振。研究了其分析行为，并将某些通用特性与量化的浆果相链接。
We propose an approach to process data from interferometric measurements on a closed quantum system at random times. For this purpose a time correlation matrix is introduced which enables us to extract dynamical properties of the quantum system. After defining a generalized expectation value we obtain a distribution of time scales, an average transition time and a correlation time. A classical limit exists which is separated from the quantum fluctuations. The latter are characterized by resonances associated with poles of the generalized expectation value. Its analytic behavior is studied and some generic properties are linked to a quantized Berry phase.
