An atom chip interferometer that could detect quantum gravity

Physicists have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. Physicists describe how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications.
