One strategy to the discrimination problem is to identify the state with certainty, leaving a possibility of undecidability. This paper gives an upper bound for the maximal success probability of unambiguous discrimination among n states. This bound coincides with the known IDP limit when two states are considered. © 2001 The American Physical Society.
