Reexamination of the optimal Bayes cost in the binary decision problem

By Bernhard 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 given by the Helstrom bound. A new strategy is introduced by inserting an impenetrable barrier in the middle of the square well,... Show more
