Abstract

It is shown how to discriminate between overcomplete sets of quantum states wish minimum error probabilities. It is not possible to distinguish reliably between nonorthogonal states, but given a specific set of N states (N>2 for a two-state system), it is necessary to analyze how well they can be distinguished. This analysis will depend on whatever output is needed, the minimum error or the maximum information.
