    "abstract": "We show that the entropy of entanglement of a state characterizes its ability\nto teleport. In particular, in order to teleport faithfully an unknown quantum\n$N$-state, the two users must share an entangled state with at least $\\log_2 N$\nbits entropy of entanglement. We also note that the maximum capacity for a\nmixed state ${\\cal M}$ to teleport equals the maximum amount of entanglement\nentropy that can be distilled out from ${\\cal M}$. Our result, therefore,\nprovides an alternative interpretation for entanglement purification.",
