Hyperentanglement in intermediate phase-space planes: benchmarking a photon-pair source for quantum key distribution
Murilo H. Magiotto, Millena B. Novaes, Wesley B. Cardoso +5
We characterize a source of photon pairs simultaneously entangled in polarization and in the transverse spatial degree of freedom, with the spatial measurements performed in interm…
Localization POVMs and intrinsic temporal uncertainty
E. R. F. Taillebois, A. T. Avelar
The causality issues concerning the localization of relativistic quantum systems, as evidenced by Hegerfeld's paradox, are addressed through a proper-time formalism of single-parti…
A new view on spin reduced density matrix for relativistic particles
E. R. F. Taillebois, A. T. Avelar
We present a new interpretation for reduced density matrices of secondary variables in relativistic systems via an analysis of Wigner's method to construct the irreducible unitary…
A proposal to implement a quantum delayed choice experiment assisted by a cavity QED
N. G. de Almeida, A. T. Avelar, W. B. Cardoso
We propose a scheme feasible with current technology to implement a quantum delayed-choice experiment in the realm of cavity QED. Our scheme uses two-level atoms interacting on and…
Bohmian trajectories for bipartite entangled states
A. R de Almeida, M. A. de Ponte, W. B. Cardoso +3
We derive Bohm's trajectories from Bell's beables for arbitrary bipartite systems composed by dissipative noninteracting harmonic oscillators at finite temperature. As an applicati…
Controlling Statistical Properties of a Cooper Pair Box Interacting with a Nanomechanical Resonator
C. Valverde, A. T. Avelar anda B. Baseia
We investigate the quantum entropy, its power spectrum, and the excitation inversion of a Cooper pair box interacting with a nanomechanical resonator, the first initially prepared…
Alternative scheme to generate a supersinglet state of three-level atoms
W. -C. Qiang, W. B. Cardoso, A. T. Avelar +1
In this paper we propose an alternative scheme to generate a supersinglet state of three three-level atoms via a single-mode of a cavity QED based on the two-photon transitions des…
Modulation of breathers in the three-dimensional nonlinear Gross-Pitaevskii equation
A. T. Avelar, D. Bazeia, W. B. Cardoso
In this paper we present analytical breather solutions of the three-dimensional nonlinear generalized Gross-Pitaevskii equation. We use an Ansatz to reduce the three-dimensional eq…
Generation of two-photon EPR and Wstates
W. B. Cardoso, W. C. Qiang, A. T. Avelar +1
In this paper we present a scheme for generation of two-photon EPR and W states in the cavity QED context. The scheme requires only one three-level Rydberg atom and two or three ca…
