Parametrization of quantum states and the quantum state discrimination problem

Seyed Arash Ghoreishi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei

A discrimination problem consists of $N$ linearly independent pure quantum states $\Phi =\{|{\varphi }_i⟩\}$ and the corresponding occurrence probabilities $\eta =\{{\eta }_i\}$. To any such problem…
