Einstein-Podolsky-Rosen steering nonlocality in pulsed optomechanics and
macroscopic atomic ensembles    [PDF]

Q. Y. He, M. D. Reid

A specific scheme for creating Einstein-Podolsky-Rosen (EPR) entanglement between a mechan- ical oscillator and an optical pulse has been presented recently by Hofer et al [Phys. Rev. A 84, 052327 (2011)]. Recent experiments have reported detection of EPR entanglement shared between spatially separated macroscopic atomic ensembles [Krauter et al, Phys. Rev. Lett. 107, 080503 (2011) and Julsgaard et al, Nature 413, 400 (2001)]. We analyse the theory developed for these ex- periments, and propose modifications in each case, to optimise so that the EPR steering nonlocality (EPR paradox) can also be realised.
