Position and momentum entanglement of dipole-dipole interacting atoms in optical lattices: The Einstein-Podolsky-Rosen paradox on a lattice
We study a possible realization of the position- and momentum-correlated atomic pairs that are confined to adjacent sites of two mutually shifted optical lattices and are entangled via laser-induced dipole-dipole interactions. The Einstein-Podolsky-Rosen (EPR) "paradox"(1) with translational variables is then modified by lattice-diffraction effects. This "paxadox" can be verified to a high degree of accuracy in this scheme.
