Sounds more like a demonstration of an ability to detect the influence of gravitational fields at scales previously unavailable. Specifically, in testing something called the "Aharonov-Bohm influence/[effect]" previously demonstrated within EM fields and now for gravity.

The study not only reveals a famed physics effect in a new context, but also showcases the potential to study subtle effects in gravitational systems. For example, researchers aim to use this type of technique to better measure Newton’s gravitational constant, G, which reveals the strength of gravity, and is currently known less precisely than other fundamental constants of nature (SN: 8/29/18).

- mikewarot 5y agoThe wavelength of an atom (DeBroglie Wavelength) is much lower than that of a photon of visible light, so it follows that anything that makes the path of one beam even slightly longer, such as putting a mass near it, would be far more detectable in this manner. There might be a small, very hard to detect optical interference shift if the experiment were re-run with a coherent laser beam.
