Entangling Two Bose-Einstein Condensates by Stimulated Bragg Scattering
arXiv:quant-ph/0206139 · doi:10.1103/PhysRevA.67.023603
Abstract
We propose an experiment for entangling two spatially separated Bose-Einstein condensates by Bragg scattering of light. When Bragg scattering in two condensates is stimulated by a common probe, the resulting quasiparticles in the two condensates get entangled due to quantum communication between the condensates via probe beam. The entanglement is shown to be significant and occurs in both number and quadrature phase variables. We present two methods of detecting the generated entanglement.
