A note on the measures of process fidelity for non-unitary quantum operations
arXiv:1111.2478
Abstract
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.
