Interferometry of Entangled Quantum States of Light in Curved Space-Time

Description

Precision quantum interferometry provides a viable way to probe the behaviour of single photons and entangled photon pairs in gravitational fields: a domain that defies a purely Newtonian description. While currently planned experiments aiming to detect such effects at the laboratory-scale are explicable using the weak equivalence principle, larger-scale experiments have the potential to detect gravitationally induced quantum interference in which space-time curvature is not negligible. In this talk, I present the basic mechanisms underlying such experiments and explain how maximally path-entangled NOON states could be used to demonstrate Riemann curvature.
