Abstract

We propose a quantum imaging-inspired setup for measuring gravitational fields using an atom that emits a photon at one of two possible locations. The atom acquires a gravitationally induced quantum phase that it shares with the photon. By restoring the path identity of the atom after its interaction with the gravitational field, the gravitationally induced phase can be measured using photon interferometry without the need for additional measurements on the atom. Through repeated measurements with varying interferometric setups, the gravitational potential and inertial acceleration can be deduced.
