| Summary: | Tools of quantum information theory can be exploited to provide a convenient description of the phenomena
of particle mixing and flavor oscillations in terms of entanglement, a fundamental quantum resource. We extend
such a picture to the domain of quantum field theory where, due to the nontrivial nature of flavor neutrino states, the presence of antiparticles provides additional contributions to flavor entanglement. We use a suitable entanglement measure, the concurrence, that allows extracting the two-mode (flavor) entanglement from the full
multimode, multiparticle flavor neutrino states. |
