We study the information transmission through a quantum channel, defined over a continuous alphabet and losing its energy en route, in the presence of correlated noise among different channel uses. We then show that entangled inputs improve the rate of transmission of such a channel.

Abstract

We study the information transmission through a quantum channel, defined over a continuous alphabet and losing its energy en route, in the presence of correlated noise among different channel uses. We then show that entangled inputs improve the rate of transmission of such a channel.
