Privacy of a lossy bosonic memory channel
G. Ruggeri, S. Mancini
abstract: We study the security of the information transmission between two honest
parties realized through a lossy bosonic memory channel when losses are
captured by a dishonest party. We then show that entangled inputs can enhance
the private information of such a channel, which however does never overcome
that of unentangled inputs in absence of memory.
