    "abstract": "The quantum analog of the classical erasure channel provides a simple example\nof a channel whose asymptotic capacity for faithful transmission of intact\nquantum states, with and without the assistance of a two-way classical side\nchannel, can be computed exactly. We derive the quantum and classical\ncapacities for the quantum erasure channel and related channels, and compare\nthem to the depolarizing channel, for which only upper and lower bounds on the\ncapacities are known.",
