    "abstract": "The quantum formalism permits one to discriminate sometimes between any set\nof linearly-independent pure states with certainty. We obtain the maximum\nprobability with which a set of equally-likely, symmetric, linearly-independent\nstates can be discriminated. The form of this bound is examined for symmetric\ncoherent states of a harmonic oscillator or field mode.",
