Teleportation of a Bose-Einstein condensate state by controlled elastic collisions
arXiv:quant-ph/0212118 · doi:10.1103/PhysRevA.67.022307
Abstract
A protocol for teleportation of the state of a Bose-Einstein condensate trapped in a three-well potential is developed. The protocol uses hard-sphere cross-collision between the condensate modes as a means of generating entanglement. As Bell state measurement, it is proposed that a homodyne detection of the condensate quadrature is performed through Josephson coupling of the condensate mode to another mode in a neighbouring well.
