To use quantum sensing to measure the electron-proton charge difference with a precision several orders of magnitude better than current limits. The experiment will use atom interferometry and the Aharonov-Bohm effect to realize a force-free measurement of the neutrality of atoms, testing an elementary property of electric charge that is of great significance to fundamental physics.
