Optimal unambiguous state discrimination of two density matrices: A second class of exact solutions
Philippe Raynal, Norbert Lütkenhaus
We consider the Unambiguous State Discrimination (USD) of two mixed quantum states. We study the rank and the spectrum of the elements of an optimal USD measurement. This naturally…
