Abstract

The phenomenon of neutrino mixing and oscillations has a deep quantum nature, which can be conveniently described in a quantum information language. This allows for an efficient investigation of the quantum correlations involved in this phenomenon and their possible use as quantum resources. Furthemore, complete complementarity relations provide a full characterization of such correlations.

Complete complementarity relations for quantum correlations in neutrino oscillations

Victor A. S. V. Bittencourt, Massimo Blasone A, Silvio De Siena +1 more

Abstract We analyze quantum correlations and quantum coherence in neutrino oscillations. To this end, we exploit complete complementarity relations (CCR) that fully characterize the interplay between different correlations encoded in a quantum system both for pure and mixed states. We consider the CCR for neutrino oscillations both in the case of plane-waves (pure state) and of wave packets (mixed state). In this last case we find a complex structure of correlations depending on the mixing angle, and we show the connection with the non local advantage of quantum coherence, a relevant quantifier of coherence.

Complete complementarity relations for three-flavor neutrino oscillations

Victor A. S. V. Bittencourt, Massimo Blasone A, Silvio De Siena +1 more

Abstract We study quantum correlations encoded in a three-flavor neutrino system by using complete complementarity relations (CCR). Due to the presence of local coherence in two-flavor subsystems, the CCR has an additional contribution not present in the two flavor mixing case. We investigate such coherence for the three possible bipartite subsystems of the global state both for an electron and a muon neutrino system.

Flavor entanglement in neutrino oscillations in the wave packet description

Massimo Blasone A, Fabio Dell’Anno, Silvio De Siena +1 more

The wave packet approach to neutrino oscillations provides an enlightening description of quantum decoherence induced, during propagation, by localization effects. Within this approach, we show that a deeper insight into the dynamical aspects of particle mixing can be obtained if one investigates the behavior of quantum correlations associated to flavor oscillations. By identifying the neutrino three-flavor modes with (suitably defined) three-qubit modes, the exploitation of tools of quantum information theory for mixed states allows a detailed analysis of the dynamical behavior of flavor entanglement during free propagation. This provides further elements leading to a more complete understanding of the phenomenon of neutrino oscillations, and a basis for possible applicative implementations. The analysis is carried out by studying the distribution of the flavor entanglement; to this aim, we perform combined investigations of the behaviors of the two-flavor concurrence and of the logarithmic negativities associated with specific bipartitions of the three flavors.

Quantum correlations in neutrino oscillations

Massimo Blasone A, Silvio De Siena, Cristina Matrella

We investigate quantum correlations in the context of neutrino oscillations, with specific reference to Daya-Bay and MINOS experiments. We compute the non-local advantage of quantum coherence -- a valuable quantum resource -- for the two experiments, within the wave-packet approach. We find that this kind of non-local correlation may persist at long distances, when oscillations are washed out, depending on the value of the mixing angle.

Complete complementarity relations for quantum correlations in neutrino oscillations with CP violation

Massimo Blasone A, Silvio De Siena, Cristina Matrella

We characterize quantum correlations encoded in a three-flavor oscillating neutrino system by taking into account CP violation. By means of the complete complementarity relations (CCR), we study the trade-off of predictability, local coherence and nonlocal correlations by using relevant parameters given by neutrino oscillation experiments. Although the CCR describe very well the contributions associated to bipartite correlations, we explore the possible presence of genuine tripartite correlations, by exploiting polygamy relations. We also provide some observations about the nonlocal advantage of quantum coherence, a mazy quantum correlation characterizing the most valuable, nonlocal, portion of quantum coherence in a multi-partite system.
