    "abstract": "We prove that the states secretly chosen from a mixed state set can be\nperfectly discriminated if and only if these states are orthogonal. The\nsufficient and necessary condition when nonorthogonal quantum mixed states can\nbe unambiguously discriminated is also presented. Furthermore, we derive a\nseries of lower bounds on the inconclusive probability of unambiguous\ndiscrimination of states from a mixed state set with \\textit{a prior}\nprobabilities.",
