The Bayes cost in the binary decision problem
Bernhard K. Meister
The problem of quantum state discrimination between two wave functions on a ring is considered. The optimal minimum-error probability is known to be given by the Helstrom bound. A…

Reexamination of the optimal Bayes cost in the binary decision problem
Bernhard K. Meister
The problem of quantum state discrimination between two wave functions of a particle in a square well potential is considered. The optimal minimum-error probability is known to be…
