    "abstract": "We present the conditions under which probabilistic error-free discrimination\nof mixed states is possible, and provide upper and lower bounds on the maximum\nprobability of success for the case of two mixed states. We solve certain\nspecial cases exactly, and demonstrate how the problems of state filtering and\nstate comparison can be recast as problems of mixed state unambiguous\ndiscrimination.",
