    "abstract": "The information capacities and ``distillability\u0027\u0027 of a quantum channel are\nstudied in the presence of auxiliary resources. These include prior\nentanglement shared between the sender and receiver and free classical bits of\nforward and backward communication. Inequalities and trade-off curves are\nderived. In particular an alternative proof is given that in the absence of\nfeedback and shared entanglement, forward classical communication does not\nincrease the quantum capacity of a channel.",
