We study the effects of non-standard neutrino matter interactions on the coherence of oscillating neutrino-system in a model independent way in the context of upcoming DUNE experiment. We find that the LMA-LIGHT solution (with normal ordering of mass eigenstates) decreases the coherence in the system in comparison to the standard model prediction for almost all values of neutrino energy E and CP violating phase $$\delta $$. However, a large enhancement in coherence parameter in the entire $$(E-\delta )$$ plane is possible for the DARK octant of $$\theta _{12}$$ for inverted ordering, with a protuberant enhancement at $$E \sim $$ 4 GeV, where maximum neutrino flux is expected in the DUNE experiment. Such features make neutrino a promising candidate for carrying out quantum information theoretic tasks. © Springer Nature Singapore Pte Ltd 2020.
