Minimum output entropy of Gaussian channels
S. Lloyd, V. Giovannetti, L. Maccone +2
We show that the minimum output entropy for all single-mode Gaussian channels is additive and is attained for Gaussian inputs. This allows the derivation of the channel capacity fo…
The bosonic minimum output entropy conjecture and Lagrangian minimization
S. Lloyd, V. Giovannetti, L. Maccone +8
We introduce a new form for the bosonic channel minimal output entropy conjecture, namely that among states with equal input entropy, the thermal states are the ones that have slig…
Confidential direct communications: a quantum approach using continuous variables
Stefano Pirandola, Samuel L. Braunstein, Seth Lloyd +1
We consider the problem of privacy in direct communications, showing how quantum mechanics can be useful to guarantee a certain level of confidentiality. In particular, we review a…
