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…
Transmittivity measurements by means of squeezed vacuum light
V. D'Auria, C. de Lisio, A. Porzio +2
A method for measuring the transmittivity of optical samples by using squeezed--vacuum radiation is illustrated. A squeezed vacuum field generated by a below--threshold optical par…
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…
Characterization of bipartite states using a single homodyne detector
Virginia D'Auria, Alberto Porzio, Salvatore Solimeno +2
We suggest a scheme to reconstruct the covariance matrix of a two-mode state using a single homodyne detector plus a polarizing beam splitter and a polarization rotator. It can be…
Trapped ions interacting with laser fields: a perturbative analysis without rotating wave approximation
P. Aniello, V. Man'ko, G. Marmo +3
The Hamiltonian describing a single ion placed in a potential trap in interaction with a laser beam is studied by means of a suitable perturbative approach. It is shown, in particu…
