| contents | The interface between quantum theory and gravity represents still uncharted territory. Recently, some works suggested promising alternative approaches aimed at witnessing quantum features to test the fundamental nature of gravity in tabletop experiments: Two masses in an initial superposition of spatially localized states are allowed to interact only through gravity and it is measured whether the final state is entangled. Here we show that one can generate the same amount of entanglement in this setup by using classical time evolution given by Newton's laws of motion. We argue that theories of quantum gravity that can be approximated by the Newtonian potential and classical time evolution given by Newton's laws of motion will generate gravity-mediated entanglement. |
