We investigate the effect of quantum decoherence and relaxation in neutrino oscillations using MINOS and T2K data. The formalism of open quantum systems is used describe the interaction of a neutrino system with the environment, where the strength of the interaction is regulated by a decoherence parameter Γ. We assume an energy dependence parameterized by Γ = γ 0 (E/GeV) n , with n = −2, 0, +2, and study three different scenarios. The MINOS and T2K data present a complementary behavior, with regard to our theoretical model, resulting in a better sensitivity for n = +2 and n = −2, respectively. We perform a combined analysis of both experimental data and include a reactor constraint on sin 2 θ 13 . The results of our combined analyses improve significantly the previous bounds on γ 0 for n = −2, reporting an upper bound of 1.7 × 10 −23 GeV, at the 90% confidence level.

“…The discovery of neutrino oscillations was the first evidence in favour of physics beyond the Standard Model, obviously attracting the particle community [16]. Complementary studies of neutrino oscillations from the perspective of quantum information and communication are naturally supported by an effective description of neutrinos, after limiting to a simplified two-flavour model, as a qubit [4,10,12,13,[17][18][19]. The time evolution of a neutrino qubit originates from a fundamental non-correspondence between the neutrino's flavour {|ν e , |ν µ } and massive states |1 , |2 .…”

Oscillation of two-flavour neutrinos is considered within a quantum mechanical framework of consistent (decoherent) dynamic histories. We investigate how consistency of selected three-time histories is affected by oscillation parameters. We show that the presence of normal matter is crucial to maintain consistency of certain classes of neutrinos’ dynamic histories and that the consistency does not depend on a Majorana phase and remains insensitive to a potential CP violation.

“…Bell to develop the famous Bell inequity (BI) [20], the violation of which rules out the hypothesis of the hidden variable theory as an alternative of quantum mechanics. The Bell type inequalities have been a subject matter of various works, for example, in optical and electronic systems [21][22][23][24], in particle physics systems such as mesons [25,26] and neutrinos [27][28][29][30][31][32][33][34][35]. A time analog of the Bell inequality, known as Legget-Garg inequality has gained a lot of attention recently [36,37].…”

Quantum correlations in neutrino oscillations in curved spacetime

Gravity induced neutrino-antineutrino oscillations are studied in the context of one and two flavor scenarios. This allows one to investigate the particle-antiparticle correlations in two and four level systems, respectively. Flavor entropy is used to probe the entanglement in the system. The well known witnesses of non-classicality such as Mermin and Svetlichly inequalities are investigated. Since the extent of neutrino-antineutrino oscillation is governed by the strength of the gravitational field, the behavior of non-classicality shows interesting features as one varies the strength of the gravitational field. Specifically, the suppression of the entanglement with the increase of the gravitational field is observed which is witnessed in the form of decrease in the flavor entropy of the system. The features of the Mermin and the Svetlichny inequalities allow one to make statements about the degeneracy of neutrino mass eigenstates.
