Classical and quantum capacities of a fully correlated amplitude damping channel
Published 9 Sep 2013 in quant-ph | (1309.2219v3)
Abstract: We study information transmission over a fully correlated amplitude damping channel acting on two qubits. We derive the single-shot classical channel capacity and show that entanglement is needed to achieve the channel best performance. We discuss the degradability properties of the channel and evaluate the quantum capacity for any value of the noise parameter. We finally compute the entanglement-assisted classical channel capacity.
