TL;DR

This paper explores how neutrino oscillations at JUNO can test the Born rule and Sorkin's triple-path interference, offering a novel and direct way to investigate fundamental quantum mechanics principles.

Contribution

It demonstrates that neutrino oscillations provide a new, boundary-condition independent method to test the Born rule via Sorkin's triple-path interference at JUNO.

Findings

Expected bounds on triple-path interference comparable to electromagnetic probes

Neutrino probes are more direct and boundary-condition independent

Potential to test foundational quantum mechanics principles

Abstract

We argue that neutrino oscillations at JUNO offer a unique opportunity to study Sorkin's triple-path interference, which is predicted to be zero in canonical quantum mechanics by virtue of the Born rule. In particular, we compute the expected bounds on triple-path interference at JUNO and demonstrate that they are comparable to those already available from electromagnetic probes. Furthermore, the neutrino probe of the Born rule is much more direct due to an intrinsic independence from any boundary conditions, whereas such dependence on boundary conditions is always present in the case of electromagnetic probes. Thus, neutrino oscillations present an ideal probe of this aspect of the foundations of quantum mechanics.
