Information transmission through lossy bosonic memory channels
arXiv:quant-ph/0502093 · doi:10.1209/epl/i2005-10041-3
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.
