Phys. Rev. A 67, 013607 (2003) [11 pages]Many-particle entanglement in two-component Bose-Einstein condensatesReceived 16 May 2002; published 23 January 2003 We investigate schemes to dynamically create many-particle entangled states of a two-component Bose-Einstein condensate in a very short time proportional to 1/N, where N is the number of condensate particles. For small N we compare exact numerical calculations with analytical semiclassical estimates and find very good agreement for N>~50. We also estimate the effect of decoherence on our scheme, study possible scenarios for measuring the entangled states, and investigate experimental imperfections. © 2003 The American Physical Society URL:
