    "abstract": "We consider one copy of a quantum system prepared with equal prior\nprobability in one of two non-orthogonal entangled states of multipartite\ndistributed among separated parties. We demonstrate that these two states can\nbe optimally distinguished in the sense of conclusive discrimination by local\noperations and classical communications(LOCC) alone. And this proves strictly\nthe conjecture that Virmani et.al. [8] confirmed numerically and analytically.\nGenerally, the optimal protocol requires local POVM operations which are\nexplicitly constructed. The result manifests that the distinguishable\ninformation is obtained only and completely at the last operation and all prior\nones give no information about that state.",
