    "abstract": "The additivity of both the entanglement of formation and the classical\nchannel capacity is known to be a consequence of the strong superadditivity\nconjecture. We show that, conversely, the strong superadditivity conjecture\nfollows from the additivity of the entanglement of formation; this means that\nthe two conjectures are equivalent and that the additivity of the classical\nchannel capacity is a consequence of them.",
