Quantum nonlocality tests with ultracold atoms (ARC Discovery Project administered by ANU) (2012–2014)
Abstract:
By demonstrating Einstein-Podolsky-Rosen `entanglement¿ and violations of Bell¿s inequalities with
ensembles of ultracold atoms, we will test one of the fundamental premises of quantum mechanics ¿
quantum nonlocality ¿ in previously unattainable regimes. Deterministic generation of large-scale
entanglement with massive particles will be a significant step toward understanding the properties of
mesoscopic and macroscopic superpositions of massive particles, since they introduce couplings to
gravitational fields, not previously tested in quantum optics experiments. There are practical applications as
well, such as in precision measurement and the design of improved atom interferometers for remote
gravitational sensing and navigation.
