NMR Relaxation by Redfield's equation in a spin system
A. Consuelo-Leal, A. G. Araujo-Ferreira, E. Lucas-Oliveira +2
Redfield's master equation is solved analytically for a nuclear system with spin . The solutions of each density matrix element are computed using the irreducible tensor ope…
Mixed states driven by Non-Hermitian Hamiltonians of a nuclear spin ensemble
D. Cius, A. Consuelo-Leal, A. G. Araujo-Ferreira +1
We study the quantum dynamics of a non-interacting spin ensemble under the effect of a reservoir by applying the framework of the non-Hermitian Hamiltonian operators. Theoretically…
NMR Hamiltonian as an effective Hamiltonian to generate Schrödinger's cat states
A. Consuelo-Leal, A. G. Araujo-Ferreira, E. L. G. Vidoto +3
This report experimentally demonstrates that the theoretical background of the atom-field scenario points out that the NMR quadrupolar Hamiltonian works as an effective Hamiltonian…
Pore Network and Medial Axis simultaneous extraction through Maximal Ball Algorithm
Mariane Barsi-Andreeta, Everton Lucas-Oliveira, Arthur Gustavo de Araujo-Ferreira +2
Network Extraction algorithms from X-ray microcomputed tomography have become a routine method to obtain pore connectivity and pore morphology information from porous media. The ma…
Pareto-optimal solution for the quantum battle of the sexes
Adriane Consuelo da Silva Leal, Arthur Gustavo de Araujo Ferreira, Everton Lucas de Oliveira +2
Quantum games have gained much popularity in the last two decades. Many of these quantum games are a redefinition of iconic classical games to fit the quantum world, and they gain…
Spin squeezing in an ensemble of quadrupolar nuclei NMR system
R. Auccaise, A. G. Araujo-Ferreira, R. S. Sarthour +3
We have characterized spin-squeezed states produced at a temperature of on a Nuclear Magnetic Resonance (NMR) quadrupolar system. The implementation is carrie…
Classical bifurcation in a quadrupolar NMR system
A. G. Araujo-Ferreira, R. Auccaise, R. S. Sarthour +3
The Josephson Junction model is applied to the experimental implementation of classical bifurcation in a quadrupolar Nuclear Magnetic Resonance system. There are two regimes, one l…
Quantum state tomography and quantum logical operations in a three qubits NMR quadrupolar system
A. G. Araujo-Ferreira, Carlos Alexandre Brasil, D. O. Soares-Pinto +3
In this work, we present an implementation of quantum logic gates and algorithms in a three effective qubits system, represented by a (I = 7/2) NMR quadrupolar nuclei. To implement…
