Nonlocal properties of entangled two-photon generalized binomial states in two separate cavities
R. Lo Franco, G. Compagno, A. Messina +1
We consider entangled two-photon generalized binomial states of the electromagnetic field in two separate cavities. The nonlocal properties of this entangled field state are analyz…
Bell's inequality violation for entangled generalized Bernoulli states in two spatially separate cavities
R. Lo Franco, G. Compagno, A. Messina +1
We consider the entanglement of orthogonal generalized Bernoulli states in two separate single-mode high- cavities. The expectation values and the correlations of the electric f…
Entanglement dynamics of two independent qubits in environments with and without memory
B. Bellomo, R. Lo Franco, G. Compagno
A procedure to obtain the dynamics of independent qudits (-level systems) each interacting with its own reservoir, for any arbitrary initial state, is presented. This is the…
Decay of nonlocality due to adiabatic and quantum noise in the solid state
B. Bellomo, G. Compagno, A. D'Arrigo +3
We study the decay of quantum nonlocality, identified by the violation of the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality, for two noninteracting Josephson qubits subject to…
Generation of Entangled Two-Photons Binomial States in Two Spatially Separate Cavities
R. Lo Franco, G. Compagno, A. Messina +1
We propose a conditional scheme to generate entangled two-photons generalized binomial states inside two separate single-mode high-Q cavities. This scheme requires that the two cav…
Loss of coherence and dressing in QED
B. Bellomo, G. Compagno, F. Petruccione
The dynamics of a free charged particle, initially described by a coherent wave packet, interacting with an environment, i.e. the electromagnetic field characterized by a temperatu…
Dynamics and extraction of quantum discord in a multipartite open system
B. Bellomo, G. Compagno, R. Lo Franco +2
We consider a multipartite system consisting of two noninteracting qubits each embedded in a single-mode leaky cavity, in turn connected to an external bosonic reservoir. Initially…
Entanglement degradation in the solid state: interplay of adiabatic and quantum noise
B. Bellomo, G. Compagno, A. D'Arrigo +3
We study entanglement degradation of two non-interacting qubits subject to independent baths with broadband spectra typical of solid state nanodevices. We obtain the analytic form…
Single-Shot Generation and Detection of a Two-Photon Generalized Binomial State in a Cavity
R. Lo Franco, G. Compagno, A. Messina +1
A "quasi-deterministic" scheme to generate a two-photon generalized binomial state in a single-mode high-Q cavity is proposed. We also suggest a single-shot scheme to measure the g…
Initial correlations effects on decoherence at zero temperature
B. Bellomo, G. Compagno, F. Petruccione
We consider a free charged particle interacting with an electromagnetic bath at zero temperature. The dipole approximation is used to treat the bath wavelengths larger than the wid…
Causality and Localization Operators
F. Buscemi, G. Compagno
The evolution of the expectation values of one and two points scalar field operators and of positive localization operators, generated by an istantaneous point source is non local.…
Distillation of Entanglement between Distant Systems by Repeated Measurements on Entanglement Mediator
G. Compagno, A. Messina, H. Nakazato +3
A recently proposed purification method, in which the Zeno-like measurements of a subsystem can bring about a distillation of another subsystem in interaction with the former, is u…
Generating and Revealing a Quantum Superposition of Electromagnetic Field Binomial States in a Cavity
R. Lo Franco, G. Compagno, A. Messina +1
We introduce the -photon quantum superposition of two orthogonal generalized binomial states of electromagnetic field. We then propose, using resonant atom-cavity interactions,…
