Tunable non-Gaussian resources for continuous-variable quantum technologies
F. Dell'Anno, D. Buono, G. Nocerino +4
We introduce and discuss a set of tunable two-mode states of continuous-variable systems, as well as an efficient scheme for their experimental generation. This novel class of tuna…
Homodyne extimation of quantum states purity by exploiting covariant uncertainty relation
V. I. Man'ko, G. Marmo, A. Porzio +2
We experimentally verify uncertainty relations for mixed states in the tomographic representation by measuring the radiation field tomograms, i.e. homodyne distributions. Thermal s…
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…
Evolution of the N ion Jaynes-Cummings model beyond the standard rotating wave approximation
P. Aniello, A. Porzio, S. Solimeno
A unitary transformation of the N-ion Jaynes-Cummings hamiltonian is proposed. It is shown that any approximate expression of the evolution operator associated with the transformed…
Resonances and spectral properties of detuned OPO pumped by fluctuating sources
A. Porzio, C. Altucci, P. Aniello +2
Twin beam fluctuations are analyzed for detuned and mismatched OPO configurations. Resonances and frequency responses to the quantum noise sources (quantum and pump amplitude/phase…
Trapped ions in laser fields: A benchmark for deformed quantum oscillators
V. Man'ko, G. Marmo, A. Porzio +2
Some properties of the non--linear coherent states (NCS), recognized by Vogel and de Matos Filho as dark states of a trapped ion, are extended to NCS on a circle, for which the Wig…
