Abstract
Quantum correlations provide a fertile testing ground for investigating fundamental aspects of quantum physics in various systems, especially in the case of relativistic (elementary) particle systems as neutrinos. In a recent paper, Ming et al. (Eur Phys J C 80:275, 2020), in connection with results of Daya-Bay and MINOS experiments, have studied the quantumness in neutrino oscillations in the framework of plane-wave approximation. We extend their treatment by adopting the wave packet approach that accounts for effects due to localization and decoherence. This leads to a better agreement with experimental results, in particular for the case of MINOS experiment.

In this paper we have extended a recent study by Ming et al [16] on quantum coherence in neutrino oscillations, by adopting a wave-packet approach, in contrast with their treatment based on plane waves
Summary
The study of quantum correlations [1] is a very active research area in view of applications such as quantum communication and computation, and quantum cryptography. In a recent article [16], Ming et al have investigated quantum correlations in neutrino oscillations by referring to Daya Bay [17,18,19], and MINOS experiments [20,21]. They found interesting results by verifying the violation of some specific bounds by quantum markers such as the nonlocal advantage of quantum coherence (NAQC), the steering and the Bell nonlocality. We extend the study of quantum correlations associated to neutrino oscillations of Ming et al [16], by adopting the wave packet approach.
