Phys. Rev. A 71, 033619 (2005) [5 pages]Maximal entanglement of two spinor Bose-Einstein condensates
Michael W. Jack1,2 and Makoto Yamashita2 Received 11 August 2004; published 16 March 2005 Starting with two weakly coupled antiferromagnetic spinor condensates, we show that by changing the sign of the coefficient of the spin interaction, U2 , via an optically induced Feshbach resonance, one can create an entangled state consisting of two anticorrelated ferromagnetic condensates. This state is maximally entangled and a generalization of the Bell state from two anticorrelated spin- 1∕2 particles to two anticorrelated spin- N∕2 atomic samples, where N is the total number of atoms. ©2005 The American Physical Society
