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 ...
Flavor mixing in quantum field theory and quantum information
(Universita degli studi di Salerno, 2011-05-10)
After reviewing the formalism for describing flavor mixing, both in Quantum Mechanics and Quantum Field Theory, some consequences along three different directions are studied. First, it is proposed that flavor mixing can ...
