Description
Entanglement of massive systems mediated by the gravitational field has been suggested as a possible signature of quantum gravity in the so-called gravity-induced entanglement (GIE) tabletop experiments. In contrast, in recent works it has been suggested that the classical propagation of the field source’s quantum degrees of freedom (through quantum-controlled classical fields) can also explain the entanglement of the masses in GIE experiments in their currently proposed regimes. We will analyze how demanding causal behaviour of the experiment can help us constraint the regimes in which GIE experiments cannot be explained via quantum controlled classical fields, opening the possibility of probing the existence of genuinely quantum degrees of freedom in the gravitational field.
