Quantum entanglement by gravity as tests of gravitational collapse models à la Diósi and Penrose

I provide a simple argument that the experimental observation of gravitationally induced entanglement rules out the validity of current gravitational collapse models. This is consistent with the recent claim to the contrary in [Trillo and Navascués, Phys. Rev. D , 111, (2025)], if one takes into account the physical constraints of actual table-top gravity experiments.

Abstract

I provide a simple argument that the experimental observation of gravitationally induced entanglement rules out the validity of current gravitational collapse models. This is consistent with the recent claim to the contrary in [Trillo and Navascués, Phys. Rev. D , 111, (2025)], if one takes into account the physical constraints of actual table-top gravity experiments.
