    "abstract": "The maximum rates for reliably transmitting classical information over\nBosonic multiple-access channels (MACs) are derived when the transmitters are\nrestricted to coherent-state encodings. Inner and outer bounds for the ultimate\ncapacity region of the Bosonic MAC are also presented. It is shown that the\nsum-rate upper bound is achievable with a coherent-state encoding and that the\nentire region is asymptotically achievable in the limit of large mean input\nphoton numbers.",
