Macroscopic quantum superposition states in Bose-Einstein condensates: Decoherence and many modes

Louis, P J Y; Brydon, Philip; Savage, Craig


The generation of macroscopic quantum superposition states in two-species dilute gas Bose-Einstein condensates was analyzed. The proposed scheme utilizes two-body interactions and Josephson coupling between the species. A dissipation model was included and a system with four modes was considered, and the generation of superposition states was found to be robust to these changes. Small number difference Schrodinger cats required either very small densities of noncondensed atoms or sophisticated...[Show more]
