Negativity of the Wigner function and thermal effects of Bell-Cat states
Vinícius N. A. Lula-Rocha, Sergio Floquet, Marco A. S. Trindade +2
We applied the Thermofield Dynamics formalism to analyze how the non-classical properties of the Bell-Cat states are influenced by a gradual change of temperature values, in a ther…
A general formulation based on algebraic spinors for the quantum computation
Marco A. S. Trindade, Sergio Floquet, J. D. M. Vianna
In this work we explore the structure of Clifford algebras and the representations of the algebraic spinors in quantum information theory. Initially we present an general formulati…
Quasitriangular Hopf algebras, braid groups and quantum entanglement
E. Pinto, Marco A. S. Trindade, J. D. M. Vianna
The aim of the paper is to provide an method to obtain representations of the braid group through a set of quasitriangular Hopf algebras. In particular, these algebras may be deriv…
Quantum Information, Thermofield Dynamics and Thermalized Bosonic Oscillator
Marco A. S. Trindade, Lourival M. Silva Filho, Leandro C. Santos +2
We show through Thermofield Dynamics approach that the action of the thermalized quantum logic gate on the thermalized state is equivalent to thermalization of the state that arise…
Restricted and unrestricted Hartree-Fock approaches for addition spectrum and Hund's rule of spherical quantum dots in a magnetic field
C. F. Destefani, J. D. M. Vianna, G. E. Marques
The Roothaan and Pople-Nesbet approaches for real atoms are adapted to quantum dots in the presence of a magnetic field. Single-particle Gaussian basis sets are constructed, for ea…
The violation of the Hund's rule in semiconductor artificial atoms
C. F. Destefani, J. D. M. Vianna, G. E. Marques
The unrestricted Pople-Nesbet approach for real atoms is adapted to quantum dots, the man-made artificial atoms, under applied magnetic field. Gaussian basis sets are used instead…
