Derives the same entanglement phase from frame dragging via Schrödinger evolution and path-integral methods in linearized gravity, including retardation effects, under locality assumptions that would imply non-classical gravity.

abstract
A recent paper published on Nature [Nature,646,813(2025)] by Aziz and Howl, claims that quantum particles become entangled when they interact gravitationally, even if the gravitational potential is treated classically. We show that the entanglement found by the authors stems from discarding some of the transition amplitudes, which, when kept, guarantee that an initially factorized state remains so over time. Therefore, no entanglement is generated by the classical gravitational interaction in the scenario considered by the authors.
