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
In their recent work, Nature, {\bf 646}, 813 (2025), Aziz and Howl claim that classical (unquantized) gravity can generate entanglement of quantized matter if matter is treated within quantum field theory which is, no doubt, our ultimate theory to use. We show that the perturbative result of Aziz and Howl in interaction picture is inconsistent with our exact and simple non-perturbative derivation in Heisenberg picture, that fundamentally precludes the claimed entanglement.

Collapse-based models of gravity are shown to be nonlocal, thereby preserving the validity of the entanglement-based witness for the non-classicality of gravity.
