Findings

Photon entanglement can be revealed or concealed by rotation.

Theoretical description of photon interferometry in non-inertial frames.

Potential for experimental tests at the quantum-relativity boundary.

Abstract

Photon interference and bunching are widely studied quantum effects that have also been proposed for high precision measurements. Here we construct a theoretical description of photon-interferometry on rotating platforms, specifically exploring the relation between non-inertial motion, relativity, and quantum mechanics. On the basis of this, we then propose an experiment where photon entanglement can be revealed or concealed solely by controlling the rotational motion of an interferometer, thus providing a route towards studies at the boundary between quantum mechanics and relativity.
