  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. (Ming et al. Eur.Phys.J.C 80 (2020) 275), 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.
