Invariant measures on multimode quantum Gaussian states
C. Lupo, S. Mancini, A. De Pasquale +3
We derive the invariant measure on the manifold of multimode quantum Gaussian states, induced by the Haar measure on the group of Gaussian unitary transformations. To this end, by…
On the transitional behavior of quantum Gaussian memory channels
C. Lupo, S. Mancini
We address the question of optimality of entangled input states in quantum Gaussian memory channels. For a class of such channels, that can be traced back to the memoryless setting…
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…
Quantum Direct Communication with Continuous Variables
Stefano Pirandola, Samuel L. Braunstein, Stefano Mancini +1
We show how continuous variable systems can allow the direct communication of messages with an acceptable degree of privacy. This is possible by combining a suitable phase-space en…
