Description
Neutrino oscillations (NOs), known for their nonclassical behavior via violations of the Leggett–Garg inequality, offer potential for quantum information applications. Motivated by recent anomalies in NO$\nu$A and T2K suggesting physics beyond the Standard Model, we explore entanglement in three-flavor NOs under the influence of off-diagonal non-standard interactions (NSIs). Focusing on the parameters $\epsilon_{e\mu}$, $\epsilon_{e\tau}$, and $\epsilon_{\mu\tau}$ with complex phases, we express Entanglement of Formation (EOF), Concurrence, and Negativity in terms of oscillation probabilities within the DUNE experimental setup. Our results show that NSI effects are strongest at low energies, with Negativity being the most sensitive across all energy ranges. While $\epsilon_{e\mu}$ and $\epsilon_{e\tau}$ primarily impact the appearance channel, $\epsilon_{\mu\tau}$ dominates the disappearance channel. Notably, Negativity shows the highest sensitivity to the CP-violating phase $\delta_{CP}$, revealing clear energy dependent structures in the [$E$ - $\delta_{CP}$] plane.
