Information transmission through lossy bosonic memory channels
Giovanna Ruggeri, Giulio Soliani, Vittorio Giovannetti, Stefano Mancini
abstract: We study the information transmission through a quantum channel, defined over
a continuous alphabet and losing its energy en route, in presence of correlated
noise among different channel uses. We then show that entangled inputs improve
the rate of transmission of such a channel.
