1. Estudo de portas lógicas quânticas de dois qubits definidas em um subespaço livre de decoerência para um sistema de quatro qubits acoplado ao resto do universo por um agente degenerado / A study of two-qubit quantum logic gates defined in a decoherence free subspaces for a four-qubit system coupled to the rest of the universe via a degenerate agent
In this dissertation we studied theoretical aspects of some recent proposals of passive quantum information processing, that is, discarding error correction protocols. Falling back upon the creation of decoherence-free subspaces through a physical system of four spins coupled to the rest of the universe by a degenerate agent, we showed to be possible to buil

2. The temperature dependence of critical current in YBa2Cu3O7-d thin films deposited on MgO by an eclipse PLD
YBa2Cu3O7-d thin films were deposited on MgO single crystals by means of an eclipse pulsed laser deposition (PLD) method. A deposited lm exhibited the critical temperature of 74 K. The dependence of critical current on temperature was well explained by the Ginzburg-Landau theory. Although the theory is described only near critical temperature, experimental r

3. Magneto-Resistência em Altos e Baixos Campos Magnéticos em Supercondutores Granulares / Magnetoresistance at low and high magnetic fields for granular superconductors
Neste trabalho foram realizadas medidas de transporte em campos magnéticos aplicados no intervalo 0 H 18 T em supercondutores granulares Sm2-xCexCuO4-y, x = 0.17 e 0.18, constituídos de ilhas supercondutoras embutidas em uma matriz isolante e pertencentes a uma transição do tipo supercondutor-isolante (SI). Amostras que apresentam coerência de fase supe

4. His-Purkinje conduction during retrograde stress.
The pattern of retrograde His-Purkinje conduction was evaluated in 28 patients using ventricular extrastimuli. In each patient progressive prolongations of His-Purkinje conduction (S2H2) which appeared as ventricular extrastimuli were induced at closer coupling intervals (S1S2). There was an inverse linear relationship of S2H2 to S1S2 which was cycle length-
