    "abstract": "Nonlocality without entanglement is an interesting field. A manifestation of\nquantum nonlocality without entanglement is the local indistinguishability of a\nset of orthogonal product states. In this paper we analyze the character of\noperators to distinguish a set of full product bases in a multi-partite system,\nand show that distinguishing perfectly a set of full product bases needs only\nlocal projective measurements and classical communication, and these\nmeasurements cannot damage each product basis. Employing these conclusions one\ncan discuss local distinguishability of full product bases easily. Finally we\ndiscuss the generalization of these results to the locally distinguishability\nof a set of incomplete product bases.",
