    "abstract": "We address the problem of unambiguous discrimination among a given set of\nquantum operations. The necessary and sufficient condition for them to be\nunambiguously distinguishable is derived in the cases of single use and\nmultiple uses respectively. For the latter case we explicitly construct the\ninput states and corresponding measurements that accomplish the task. It is\nfound that the introduction of entanglement can improve the discrimination.",
