    "abstract": "We show that the fidelity result of advantage distillation (Bennett et al,\nPhys. Rev. Lett., 76, 722(1996)) is not only for the product state of raw\npairs, it is actually correct with whatever form of state of raw pairs. We then\ngive a general theorem for unconditional entanglement purification. This\ntheorem lists the conditions on which the fidelity result of a purification\nprotocol keeps unchanged from product form of raw-pair state and arbitrary form\nof raw-pair state. Using this theorem, we find that all existing purification\npuricfication can work for arbitrary initial state of raw pairs.",
