关于非幺正量子操作过程保真度度量的注记

A note on the measures of process fidelity for non-unitary quantum operations

Joydip Ghosh

摘要:

可以在两个量子过程之间定义各种保真度度量,特别是当其中至少一个是非幺正的时。本文考虑了两种状态平均过程保真度测度,提出了一种计算它们的有效方法,并研究了它们的数学性质以及它们之间的关系。

英文摘要:

Various fidelity measures can be defined between two quantum processes especially when at least one of them is non-unitary. In this paper we consider two such measures of state averaged process fidelity, put forward an efficient procedure to compute them and investigate their mathematical properties as well as their relationship.
