    "abstract": "We investigate the capacity of bosonic quantum channels for the transmission\nof quantum information. Achievable rates are determined from measurable moments\nof the channel by showing that every channel can asymptotically simulate a\nGaussian channel which is characterized by second moments of the initial\nchannel. We calculate the quantum capacity for a class of Gaussian channels,\nincluding channels describing optical fibers with photon losses, by proving\nthat Gaussian encodings are optimal. Along the way we provide a complete\ncharacterization of degradable Gaussian channels and those arising from\nteleportation protocols.",
