# Information communicated by entangled photon pairs

@article{Brougham2012InformationCB, title={Information communicated by entangled photon pairs}, author={Thomas Brougham and Stephen M. Barnett}, journal={Physical Review A}, year={2012}, volume={85}, pages={032322} }

A key goal of quantum communication is to determine the maximum number of bits shared between two quantum systems. An important example of this is in entanglement-based quantum key distribution (QKD) schemes. A realistic treatment of this general communication problem must take account of the nonideal nature of the entanglement source and the detectors. The aim of this paper is to give such a treatment. We obtain analytic expression for the mutual information in terms of experimental parameters…

It is proved that an EPP involving one-way classical communication and acting on mixed state M (obtained by sharing halves of Einstein-Podolsky-Rosen pairs through a channel) yields a QECC on \ensuremath{\chi} with rate Q=D, and vice versa, and it is proved Q is not increased by adding one- way classical communication.
