Discrimination between non perfectly known states

Abstract

Discrimination task is treated in the case of only partial prior information from measurements of unknown states. The construction of the optimal discrimination device and estimation of unknown states is performed simultaneously. A communication through a noisy quantum channel is formulated in terms of the proposed discrimination protocol.
