AMO Seminar: Martine Schut, University of Groningen, “Entanglement-based test of Quantum Gravity and its Experimental Challenges”

In 2017 a table top experiment that uses entanglement witnessing to test the quantum nature of gravity was proposed. Following the Local Operations and Classical Communication (LOCC) principle, two initially unentangled quantum superpositions can only become entangled via a quantum mediator. Therefore, if two quantum systems that interact solely via gravity become entangled, this is a sign of the quantum nature of the graviton. This idea will briefly be discussed in the talk, after which some of the experimental challenges in realising this experiment will be discussed, mainly focussing on decoherence and environmental noise..
