    "abstract": "We propose a generalized discrimination scheme for mixed quantum states. In\nthe present scenario we allow for certain fixed fraction of inconclusive\nresults and we maximize the success rate of the quantum-state discrimination.\nThis protocol interpolates between the Ivanovic-Dieks-Peres scheme and the\nHelstrom one. We formulate the extremal equations for the optimal positive\noperator valued measure describing the discrimination device and establish a\ncriterion for its optimality. We also devise a numerical method for efficient\nsolving of these extremal equations.",
