    "abstract": "We obtain a necessary and sufficient condition for a finite set of states of\na finite dimensional multiparticle quantum system to be amenable to unambiguous\ndiscrimination using local operations and classical communication. This\ncondition is valid for states which may be be mixed, entangled or both. When\nthe support of the set of states is the entire multiparticle Hilbert space,\nthis condition is found to have an intriguing connection with the theory of\nentanglement witnesses.",
