Non-divisiblity and non-Markovianity in a Gaussian dissipative dynamics
Fabio Benatti, Roberto Floreanini, Stefano Olivares
We study a stochastic Schroedinger equation that generates a family of Gaussian dynamical maps in one dimension permitting a detailed exam of two different definitions of non-Marko…
Entanglement robustness and geometry in systems of identical particles
F. Benatti, R. Floreanini, U. Marzolino
The robustness properties of bipartite entanglement in systems of N bosons distributed in M different modes are analyzed using a definition of separability based on commuting algeb…
Optical interferometry in the presence of large phase diffusion
Marco G. Genoni, Stefano Olivares, Davide Brivio +5
Phase diffusion represents a crucial obstacle towards the implementation of high precision interferometric measurements and phase shift based communication channels. Here we presen…
Indirect Controllability of Quantum Systems; A Study of Two Interacting Quantum Bits
Domenico D'Alessandro, Raffaele Romano
A quantum mechanical system S is indirectly controlled when the control affects an ancillary system A and the evolution of S is modified through the interaction with A only. A stud…
Bipartite entanglement in systems of identical particles: the partial transposition criterion
F. Benatti, R. Floreanini, U. Marzolino
We study bipartite entanglement in systems of N identical bosons distributed in M different modes. For such systems, a definition of separability not related to any a priori Hilber…
