Quantum signatures of breather-breather interactions
J. Dorignac, J. C. Eilbeck, M. Salerno +1
The spectrum of the Quantum Discrete Nonlinear Schrödinger equation on a periodic 1D lattice shows some interesting detailed band structure which may be interpreted as the quantum…
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…
Minimum decoherence cat-like states in Gaussian noisy channels
A. Serafini, S. De Siena, F. Illuminati +1
We address the evolution of cat-like states in general Gaussian noisy channels, by considering superpositions of coherent and squeezed-coherent states coupled to an arbitrarily squ…
Determination of continuous variable entanglement by purity measurements
Gerardo Adesso, Alessio Serafini, Fabrizio Illuminati
We classify the entanglement of two--mode Gaussian states according to their degree of total and partial mixedness. We derive exact bounds that determine maximally and minimally en…
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…
Symplectic invariants, entropic measures and correlations of Gaussian states
Alessio Serafini, Fabrizio Illuminati, Silvio De Siena
We present a derivation of the Von Neumann entropy and mutual information of arbitrary two--mode Gaussian states, based on the explicit determination of the symplectic eigenvalues…
Numerical simulation of nonunitary gravity-induced localization
Sergio De Filippo, Filippo Maimone, Anton Luca Robustelli
The localization of a quantum state is numerically exhibited in a nonunitary Newtonian model for gravity. It is shown that an unlocalized state of a ball of mass just above the exp…
Purity of Gaussian states: measurement schemes and time-evolution in noisy channels
M. G. A. Paris, F. Illuminati, A. Serafini +1
We present a systematic study of the purity for Gaussian states of single-mode continuous variable systems. We prove the connection of purity to observable quantities for these sta…
Quantum limit of deterministic theories
M. Blasone, P. Jizba, G. Vitiello
We show that the quantum linear harmonic oscillator can be obtained in the large limit of a classical deterministic system with SU(1,1) dynamical symmetry. This is done in anal…
Dissipation, Emergent Quantization and Quantum Fluctuations
M. Blasone, P. Jizba, G. Vitiello
We review some aspects of the quantization of the damped harmonic oscillator. We derive the exact action for a damped mechanical system in the frame of the path integral formulatio…
Quantum dissipation induced noncommutative geometry
S. Sivasubramanian, Y. N. Srivastava, G. Vitiello +1
The quantum statistical dynamics of a position coordinate x coupled to a reservoir requires theoretically two copies of the position coordinate within the reduced density matrix de…
