Coherently controlled entanglement generation in a binary Bose-Einstein condensate
arXiv:cond-mat/0702241 · doi:10.1209/0295-5075/78/10009
Abstract
Considering a two-component Bose-Einstein condensate in a double-well potential, a method to generate a Bell state consisting of two spatially separated condensates is suggested. For repulsive interactions, the required tunnelling control is achieved numerically by varying the amplitude of a sinusoidal potential difference between the wells. Both numerical and analytical calculations reveal the emergence of a highly entangled mesoscopic state.
