Description
The Leggett-Garg Inequality (LGI) offers a way to test for the violations of classicality in a system by studying how its measurements are correlated over time. Long-baseline neutrino oscillation experiments provide some of the longest distances over which the quantum behavior of any system can be tested. In this talk, I will present a data-driven study of LGI violations using MINOS, NOvA, and T2K data, together with projections for DUNE. We include experimental uncertainties and compare the quantum predictions with classical expectations to quantify the statistical significance. Among these experiments, we find that T2K gives the most significant violation of classicality at the level of about $14\sigma$, while NOvA and DUNE also show a significance greater than $5\sigma$.
