    "abstract": "In a 1991 paper, Asher Peres and the author theoretically analyzed a set of\nunentangled bipartite quantum states that could apparently be distinguished\nbetter by a global measurement than by any sequence of local measurements on\nthe individual subsystems. The present paper returns to the same example, and\nshows that the best result so far achieved can alternatively be attained by a\nmeasurement that, while still global, is \"unentangled\" in the sense that the\noperator associated with each measurement outcome is a tensor product.",
