Continuous Variable Quantum Cryptography using Two-Way Quantum Communication
Stefano Pirandola, Stefano Mancini, Seth Lloyd +1
Quantum cryptography has been recently extended to continuous variable systems, e.g., the bosonic modes of the electromagnetic field. In particular, several cryptographic protocols…
Stationary entanglement between two movable mirrors in a classically driven Fabry-Perot cavity
David Vitali, Stefano Mancini, Paolo Tombesi
We consider a Fabry-Perot cavity made by two moving mirrors and driven by an intense classical laser field. We show that stationary entanglement between two vibrational modes of th…
Optimal control of entanglement via quantum feedback
Stefano Mancini, Howard M. Wiseman
It has recently been shown that finding the optimal measurement on the environment for stationary Linear Quadratic Gaussian control problems is a semi-definite program. We apply th…
Quantum Gaussian Channels with Additive Correlated Classical Noise
Giovanna Ruggeri, Stefano Mancini
We provide a model to study memory effects in quantum Gaussian channels with additive classical noise over an arbitrary number of uses. The correlation among different uses is intr…
A probabilistic approach to quantum mechanics based on tomograms
Michele Caponigro, Stefano Mancini, Vladimir I. Man'ko
It is usually believed that a picture of Quantum Mechanics in terms of true probabilities cannot be given due to the uncertainty relations. Here we discuss a tomographic approach t…
Two-way Protocol for Quantum Cryptography with Imperfect Devices
M. Lucamarini, A. Cere', G. Di Giuseppe +3
The security of a deterministic quantum scheme for communication, namely the LM05 [1], is studied in presence of a lossy channel under the assumption of imperfect generation and de…
