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
