Circuit-based quantum random access memory for classical data with continuous amplitudes
Tiago M. L. de Veras, Ismael C. S. de Araujo, Daniel K. Park +1
Loading data in a quantum device is required in several quantum computing applications. Without an efficient loading procedure, the cost to initialize the algorithms can dominate t…
Systematic Oil Flow Modeling in the Quasi-3D Approximation Yields Additional Terms that Allows for Variable Cross-Section Area Tubing
Edval J. P. Santos
A systematic model development for oil flow in quasi-3D (1D + 2D) is presented. Our approach provides a unified modeling scheme. Besides, additional terms are obtained, which allow…
Predicting Short-term Mobile Internet Traffic from Internet Activity using Recurrent Neural Networks
Guto Leoni Santos, Pierangelo Rosati, Theo Lynn +3

Statistical complexity is maximized close to criticality in cortical dynamics
Nastaran Lotfi, Thaís Feliciano, Leandro A. A. Aguiar +6
Complex systems are typically characterized as an intermediate situation between a complete regular structure and a random system. Brain signals can be studied as a striking exampl…
Interfacial instabilities in two-dimensional Stokes flow: a weakly nonlinear analysis
Gabriel Dias Carvalho, Rodolfo Brandão, José A. Miranda
Two-dimensional Stokes flow with injection and suction is investigated through a second-order, perturbative mode-coupling approach. We examine the time-dependent disturbance of an…
Decay of quantumness in a measurement process: Action of a coarse-graining channel
Gabriel Dias Carvalho, Pedro Silva Correia
A model of a quantum measurement process is presented: a system consisting of a qubit in a superposition interacts with a measuring apparatus consisting of a N qubit state. Looking…
Magnon-mediated spin currents in Tm3Fe5O12/Pt with perpendicular magnetic anisotropy
G. L. S. Vilela, J. E. Abrao, E. Santos +7
The control of pure spin currents carried by magnons in magnetic insulator (MI) garnet films with a robust perpendicular magnetic anisotropy (PMA) is of great interest to spintroni…
