    "abstract": "Entanglement bits or ``ebits\u0027\u0027 have been proposed as a quantitative measure\nof a fundamental resource in quantum information processing. For such an\ninterpretation to be valid, it is important to show that the same number of\nebits in different forms or concentrations are inter-convertible in the\nasymptotic limit. Here we draw attention to a very important but hitherto\nunnoticed aspect of entanglement manipulation --- the classical communication\ncost. We construct an explicit procedure which demonstrates that for bi-partite\npure states, in the asymptotic limit, entanglement can be concentrated or\ndiluted with vanishing classical communication cost. Entanglement of bi-partite\npure states is thus established as a truly inter-convertible resource.",
