Article overview

Entanglement enhanced information transmission over a quantum channel with correlated noise
Chiara Macchiavello ; G.Massimo Palma ;
Date:	9 Jul 2001
Subject:	quant-ph
Abstract:	We show that entanglement is a useful resource to enhance the mutual information of the depolarizing channel when the noise on consecutive uses of the channel has some partial correlations. We obtain a threshold in the degree of memory, depending on the shrinking factor of the channel, above which a higher amount of classical information is transmitted with entangled signals.
