Different operational meanings of continuous variable Gaussian entanglement criteria and Bell inequalities
D. Buono, G. Nocerino, S. Solimeno +1
Entanglement, one of the most intriguing aspects of quantum mechanics, marks itself into different features of quantum states. For this reason different criteria can be used for ve…
Experimental analysis of decoherence of quantumness in a continuous variables bi-partite entangled system
D. Buono, G. Nocerino, A. Porzio +1
Quantum properties are soon subject to decoherence once the quantum system interacts with the classical environment. In this paper we experimentally test how propagation losses, in…
Non-Gaussian states produced by close-to-threshold optical parametric oscillators: role of classical and quantum fluctuations
Virginia D'Auria, Corrado de Lisio, Alberto Porzio +3
Quantum states with non-Gaussian statistics generated by optical parametric oscillators (OPO) with fluctuating parameters are studied by means of the Kurtosis excess of the externa…
An effective method to estimate multidimensional Gaussian states
J. Rehacek, S. Olivares, D. Mogilevtsev +6
A simple and efficient method for characterization of multidimensional Gaussian states is suggested and experimentally demonstrated. Our scheme shows analogies with tomography of f…
Full characterization of Gaussian bipartite entangled states by a single homodyne detector
V. D'Auria, S. Fornaro, A. Porzio +3
We present the full experimental reconstruction of Gaussian entangled states generated by a type--II optical parametric oscillator (OPO) below threshold. Our scheme provides the en…
Optical response of a misaligned and suspended Fabry-Perot cavity
G. Cella, A. Di Virgilio, P. La Penna +4
The response to a probe laser beam of a suspended, misaligned and detuned optical cavity is examined. A five degree of freedom model of the fluctuations of the longitudinal and tra…
