Uhlmann holonomy的操作方法
Operational approach to the Uhlmann holonomy
摘要:
我们提出了一个密度算符的乌尔曼振幅的物理解释。鉴于这种解释,我们提出了一种操作方法来获得平行的乌尔曼条件。这使我们能够实现并行传输沿一系列的密度算子的迭代准备过程。在最后一步,所得到的乌尔曼完整性可以通过干涉测量来确定。
英文摘要:
We suggest a physical interpretation of the Uhlmann amplitude of a density operator. Given this interpretation we propose an operational approach to obtain the Uhlmann condition for parallelity. This allows us to realize parallel transport along a sequence of density operators by an iterative preparation procedure. At the final step the resulting Uhlmann holonomy can be determined via interferometric measurements.
