Phys. Rev. A 71, 033619 (2005) [5 pages]Maximal entanglement of two spinor Bose-Einstein condensatesReceived 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 URL:
