    "abstract": "All communication channels are at bottom quantum mechanical. Quantum\nmechanics contributes both obstacles to communication in the form of noise, and\nopportunities in the use of intrinsically quantum representations for\ninformation. This paper investigates the trade-off between power and\ncommunication rate for coupled quantum channels. By exploiting quantum\ncorrelations such as entanglement, coupled quantum channels can communicate at\na potentially higher rate than unentangled quantum channels given the same\npower. In particular, given the same overall power, M coupled, entangled\nquantum channels can send M bits in the same time it takes a single channel to\nsend a single bit, and in the same time it takes M unentangled channels to send\n$\\sqrt M$ bits.",
