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…
Dynamics of localized solutions in three core coupled waveguides with quasi-periodic nonlinearity
Bruno M. Miranda, Ardiley T. Avelar, Wesley B. Cardoso +1
In this paper we investigate the behavior of localized solutions, specifically solitons, in a system of three coupled waveguides. The nonlinearity is modeled by a quasi-periodic mo…
Analyzing lump-type solutions in scalar field models through configurational information measure
Marcelo A. Feitosa, Wesley B. Cardoso, Dionisio Bazeia +1
In this paper we employ a configurational information measure, specifically the differential configurational complexity (DCC), to quantify the information content of lump-type solu…
Optical Algorithm for Derivative of Real-Valued Functions
Murilo H. Magiotto, Guilherme L. Zanin, Wesley B. Cardoso +2
The derivation of a function is a fundamental tool for solving problems in calculus. Consequently, the motivations for investigating physical systems capable of performing this tas…
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…
Effective equations for repulsive quasi-1D BECs trapped with anharmonic transverse potentials

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…
