    "abstract": "A new protocol for quantum broadcast channels based on the fully quantum\nSlepian-Wolf protocol is presented. The protocol yields an achievable rate\nregion for entanglement-assisted transmission of quantum information through a\nquantum broadcast channel that can be considered the quantum analogue of\nMarton\u0027s region for classical broadcast channels. The protocol can be adapted\nto yield achievable rate regions for unassisted quantum communication and for\nentanglement-assisted classical communication; in the case of unassisted\ntransmission, the region we obtain has no independent constraint on the sum\nrate, only on the individual transmission rates. Regularized versions of all\nthree rate regions are provably optimal.",
