Decoherence of number states in phase-sensitive reservoirs
A. Serafini, S. De Siena, F. Illuminati
The non-unitary evolution of initial number states in general Gaussian environments is solved analytically. Decoherence in the channels is quantified by determining explicitly the…
Dynamics of entanglement between two atomic samples with spontaneous scattering
Antonio Di Lisi, Silvio De Siena, Fabrizio Illuminati
We investigate the effects of spontaneous scattering on the evolution of entanglement of two atomic samples, probed by phase shift measurements on optical beams interacting with bo…
Entanglement and purity of two-mode Gaussian states in noisy channels
Alessio Serafini, Fabrizio Illuminati, Matteo G. A. Paris +1
We study the evolution of purity, entanglement and total correlations of general two--mode Gaussian states of continuous variable systems in arbitrary uncorrelated Gaussian environ…
Structure of multiphoton quantum optics. I. Canonical formalism and homodyne squeezed states
Fabio Dell'Anno, Silvio De Siena, Fabrizio Illuminati
We introduce a formalism of nonlinear canonical transformations for general systems of multiphoton quantum optics. For single-mode systems the transformations depend on a tunable f…
Structure of multiphoton quantum optics. II. Bipartite systems, physical processes, and heterodyne squeezed states
Fabio Dell'Anno, Silvio De Siena, Fabrizio Illuminati
Extending the scheme developed for a single mode of the electromagnetic field in the preceding paper ``Structure of multiphoton quantum optics. I. Canonical formalism and homodyne…
Characterizing entanglement with global and marginal entropic measures
Gerardo Adesso, Fabrizio Illuminati, Silvio De Siena
We qualify the entanglement of arbitrary mixed states of bipartite quantum systems by comparing global and marginal mixednesses quantified by different entropic measures. For syste…
