✦ Synopsis

We derive the general discrimination of quantum states chosen from a certain set, given an initial M copies of each state, and obtain the matrix inequality which describes the bound between the maximum probability of correctly determining and that of error. The former works are special cases of our results.

Since the state of a quantum system is not an observable, it cannot be determined completely, in principle, if no a priori information is available. In this case, one needs to resort to various estimation strategies. The situation is completely different if a priori knowledge is available. Even unam
