The principle of majorization: application to random quantum circuits
Raul O. Vallejos, Fernando de Melo, Gabriel G. Carlo
We test the principle of majorization [J. I. Latorre and M. A. Martin-Delgado, Phys. Rev. A 66, 022305 (2002)] in random circuits. Three classes of circuits were considered: (i) un…
Entropic Uncertainty Relations and the Quantum-to-Classical transition
Isadora Veeren, Fernando de Melo
Our knowledge of quantum mechanics can satisfactorily describe simple, microscopic systems, but is yet to explain the macroscopic everyday phenomena we observe. Here we aim to shed…
Multiparticle quantum walk with a gas-like interaction
Pedro C. S. Costa, Fernando de Melo, Renato Portugal
We analyze the dynamics of multiparticle discrete-time quantum walk on the two-dimensional lattice, with an interaction inspired on a classical model for gas collision, called HPP…
Coarse Graining of Partitioned Cellular Automata
Pedro C. S. Costa, Fernando de Melo
Partitioned cellular automata are known to be an useful tool to simulate linear and nonlinear problems in physics, specially because they allow for a straightforward way to define…
