Establishing Einstein-Poldosky-Rosen channels between nanomechanics and atomic ensembles.
We suggest interfacing nanomechanical systems via an optical quantum bus to atomic ensembles, for which means of high precision state preparation, manipulation, and measurement are available. This allows, in particular, for a quantum nondemolition Bell measurement, projecting the coupled system, atomic-ensemble-nanomechanical resonator, into an entangled EPR state. The entanglement is observabl...
متن کاملTowards an Einstein–Podolsky–Rosen paradox between two macroscopic atomic ensembles at room temperature
Experiments have reported the entanglement of two spatially separated macroscopic atomic ensembles at room temperature (Krauter et al 2011 Phys. Rev. Lett. 107 080503; Julsgaard et al 2001 Nature 413 400). We show how an Einstein–Podolsky–Rosen (EPR) paradox is realizable with this experiment. Our proposed test involves violation of an inferred Heisenberg uncertainty principle, which is a suffi...
متن کاملEinstein-Podolsky-Rosen correlations of ultracold atomic gases.
We demonstrate that collective continuous variables of two species of trapped ultracold bosonic gases can be Einstein-Podolsky-Rosen-correlated (entangled) via inherent interactions between the species. We propose two different schemes for creating these correlations--a dynamical scheme and a static scheme analogous to two-mode squeezing in quantum optics. We quantify the correlations by using ...
متن کاملSensitivity to thermal noise of atomic Einstein-Podolsky-Rosen entanglement
We examine the prospect of demonstrating Einstein-Podolsky-Rosen (EPR) entanglement for massive particles using spin-changing collisions in a spinor Bose-Einstein condensate. Such a demonstration has recently been attempted by Gross et al. [Nature (London) 480, 219 (2011)] using a condensate of 87Rb atoms trapped in an optical lattice potential. For the condensate initially prepared in the (F,m...
متن کاملQuantum Channels of the Einstein-podolski-rosen Kind *
An EPR-channel consists of two Hilbert spaces, H A and H B , and of a density operator sitting on the their direct product space H AB. The channel is triggered by a von Neumann measurement on H A , resulting in a state (density operator) ω A. Because a measurement in H A can be considered as a measurement in H AB equally well, it induces a new state in H AB and, hence, a new state, ω B , in H B...
