    "abstract": "We have investigated the problem of discriminating between nonorthogonal\nquantum states with least probability of error. We have determined that the\nbest strategy for some sets of states is to make no measurement at all, and\nsimply to always assign the most commonly occurring state. Conditions which\ndescribe such sets of states have been derived.",
