Abstract

Although quantum gravity is a highly pursued research topic, the more basic question of whether gravity is quantum has not yet been answered. Here we present a table-top experiment, feasible with forseeable advances in technology, which can demonstrate that the Newtonian field from an object is a bonafide quantum entity. This is demonstrated through the development of a verifiable entanglement between two matter wave interferometers with mesoscopic objects as entanglement between systems which are not directly interacting, can only be mediated by a quantum system.
