    "abstract": "An expression is derived characterizing the set of admissible rate pairs for\nsimultaneous transmission of classical and quantum information over a given\nquantum channel, generalizing both the classical and quantum capacities of the\nchannel. Although our formula involves regularization, i.e. taking a limit over\nmany copies of the channel, it reduces to a single-letter expression in the\ncase of generalized dephasing channels. Analogous formulae are conjectured for\nthe simultaneous public-private capacity of a quantum channel and for the\nsimultaneously 1-way distillable common randomness and entanglement of a\nbipartite quantum state.",
