Dissipation, mixing and two level system in quantum field theory
(Universita degli studi di Salerno, 2012-04-30)In this dissertation we discuss several aspects of a two level system (qubit) in the context of quantum mechanics and quantum field theory. The presence of geometrical phases in the evolution of a qubit state is shown. We ...
