量子态间距离的操作不变互补测量
Operationally Invariant Measure of the Distance between Quantum States by Complementary Measurements
摘要：
我们提出了一种计算两个量子态距离的方法，它反过来告诉我们它们的接近程度。这被定义为两个状态的一组完整的互补测量的部分知识的差异之和。结果表明，该测度具有运算不变性，并且与Hilbert-Schmidt距离等价。距离的操作测度为量子态之间的信息距离提供了一个很好的解释。
英文摘要：
We propose an operational measure of distance of two quantum states, which conversely tells us their closeness. This is defined as a sum of differences in partial knowledge over a complete set of mutually complementary measurements for the two states. It is shown that the measure is operationally invariant and it is equivalent to the Hilbert-Schmidt distance. The operational measure of distance provides a remarkable interpretation of the information distance between quantum states.
