Dense coding capacity of a quantum channel
Riccardo Laurenza, Cosmo Lupo, Seth Lloyd, Stefano Pirandola
Abstract
The authors consider a realistic dense coding scenario where noise is affecting both the transmission of quantum systems from the sender (Bob) to the receiver (Alice), and the distribution of the resource state from Alice to Bob. Assuming that this noise is described by the same quantum channel, the authors define its dense coding capacity by optimizing over all adaptive strategies that Alice can implement, while Bob encodes the information by means of Pauli operators.
