Fidelity for imperfect postselection

arXiv:0711.3979 · doi:10.1103/PhysRevA.76.052106

Abstract

We describe a simple measure of fidelity for mixed state postselecting devices. The measure is most appropriate for postselection where the task performed by the output is only effected by a specific state.
