Two decades ago the first data for a free-fall comparison of a quantum object and a macroscopic object has been taken, paving the way towards tests of the Universality of Free Fall in the quantum realm. Yet it was debated, whether this constitutes an atom interferometric redhsift test.
We conduct a study of tests of the Einstein Equivalence Principle with Matter Wave Interferometry with a focus on the Universality of the Gravitational Redshift and investigate experimental implementations in the VLBAI facility in Hannover. An analysis of the systematic errors lets us conclude that tests of the Universality of the Gravitational Redshift utilizing atom interferometers are in principle possible.
