    "abstract": "We derive the general formula for the capacity of a noiseless quantum channel\nassisted by an arbitrary amount of noisy entanglement. In this capacity\nformula, the ratio of the quantum mutual information and the von Neumann\nentropy of the sender\u0027s share of the noisy entanglement plays the role of\nmutual information in the completely classical case. A consequence of our\nresults is that bound entangled states cannot increase the capacity of a\nnoiseless quantum channel.",
