Generalized Bell scenarios: disturbing consequences on local-hidden-variable models
André Mazzari, Gabriel Ruffolo, Carlos Vieira +3
Bell nonlocality and Kochen-Specker contextuality are among the main topics of foundations of quantum theory. Both of them are related to stronger-than-classical correlations, with…
Exploring quantum thermodynamics with NMR
Carlos H. S. Vieira, Jefferson L. D. de Oliveira, Jonas F. G. Santos +2
Quantum thermodynamics seeks to extend non-equilibrium stochastic thermodynamics to small quantum systems where non-classical features are essential to its description. Such a rese…
Coherence behavior of strongly coupled bosonic modes
Jucelino F. Sousa, Carlos H. S. Vieira, Jonas F. G. Santos +1
We study the effect of the intermode coupling in the generation of coherence when two bosonic modes are bilinearly coupled. We consider the case for which the two modes are weakly…
Interplays between classical and quantum entanglement-assisted communication scenarios
Carlos Vieira, Carlos de Gois, Lucas Pollyceno +1
Prepare-and-measure scenarios, in their many forms, can be seen as the basic building blocks of communication tasks. As such, they can be used to analyze a diversity of classical a…
Sorkin parameter for type-I spontaneous parametric down-conversion biphotons and matter waves
F. C. V. de Brito, C. H. S. Vieira, I. G. da Paz +2
We propose experimental measurements of the logarithmic negativity, which quantifies quantum correlations using Gouy phase measurements in an asymmetric double-slit interference ex…
Coherence dynamics induced by attenuation and amplification Gaussian channels
Jonas F. G. Santos, C. H. S. Vieira
Quantum Gaussian channels play a key role in quantum information theory. In particular, the attenuation and amplification channels are useful to describe noise and decoherence effe…
Bell Non-Locality in Many Body Quantum Systems with Exponential Decay of Correlations
Carlos H. S. Vieira, Cristhiano Duarte, Raphael C. Drumond +1
Using Bell-inequalities as a tool to explore non-classical physical behaviours, in this paper we analyze what one can expect to find in many-body quantum physics. Concretely, frami…
Negativity-Mutual Information conversion and coherence in two-coupled harmonic oscillators
Jonas F. G. Santos, Carlos H. S. Vieira, Pedro R. Dieguez
Quantum information is a common topic of research in many areas of quantum physics, such as quantum communication and quantum computation, as well as quantum thermodynamics. It can…
Exotic looped trajectories in double-slit experiments with matter waves
Carlos Vieira, Helder Alexander, Gustavo de Souza +2
We study the observation of exotic looped trajectories in double-slit experiments with matter waves. We consider the relative intensity at as a function of the time-of-flight…
Gouy phase in non-classical paths in triple-slit interference experiment
Irismar da Paz, Carlos Vieira, Robert Ducharme +3
We propose a simple model to study the Gouy phase effect in the triple-slit experiment in which we consider a non-classical path. The Gouy phase differs for classical or non-classi…
