熵作为几何相位的函数

Entropy as a function of Geometric Phase

Julian Hartley, Vlatko Vedral

摘要:

在二维和三维希尔伯特空间中,我们给出了冯诺伊曼熵作为由可见度和平均可分辨度调制的几何相位的函数的封闭形式的解。我们表明,同样类型的依赖性也存在于更高的维度。我们还概述了一种方法,用于测量的熵和相位实验使用一个简单的马赫-曾德尔型干涉仪,物理上解释了为什么这两个概念是相关的。

英文摘要:

We give a closed-form solution of von Neumann entropy as a function of geometric phase modulated by visibility and average distinguishability in Hilbert spaces of two and three dimensions. We show that the same type of dependence also exists in higher dimensions. We also outline a method for measuring both the entropy and the phase experimentally using a simple Mach-Zehnder type interferometer which explains physically why the two concepts are related.
