Nonlocality of two- and three-mode continuous variable systems
A. Ferraro, M. G. A. Paris
We address nonlocality of a class of fully inseparable three-mode Gaussian states generated either by bilinear three-mode Hamiltonians or by a sequence of bilinear two-mode Hamilto…
Degaussification of twin-beam and nonlocality in the phase space
Stefano Olivares, Matteo G. A. Paris
We show that inconclusive photon subtraction (IPS) on twin-beam produces non-Gaussian states that violate Bell's inequality in the phase-space. The violation is larger than for the…
Photon statistics without counting photons
Andrea R. Rossi, Stefano Olivares, Matteo G. A. Paris
We show how to obtain the photon distribution of a single-mode field using only avalanche photodetectors. The method is based on measuring the field at different quantum efficienci…
Robust generation of entanglement in Bose-Einstein condensates by collective atomic recoil
Mary M. Cola, Matteo G. A. Paris, Nicola Piovella
We address the dynamics induced by collective atomic recoil in a Bose-Einstein condensate in presence of radiation losses and atomic decoherence. In particular, we focus on the lin…
Degradation of continuous variable entanglement in a phase-sensitive environment
Andrea R. Rossi, Stefano Olivares, Matteo G. A. Paris
We address the propagation of twin-beam of radiation through Gaussian phase-sensitive channels, i.e. noisy channels with squeezed fluctuations. We find that squeezing the environme…
About distillability of depolarized states
Andrea R. Rossi, Matteo G. A. Paris
Reduction criteria for distillability is applied to general depolarized states and an explicit condition is found in terms of a characteristic polynomial of the density matrix. 3 $…
