Phys. Rev. A 69, 053608 (2004) [5 pages]Quantum entanglement of many atoms in spinor Bose-Einstein condensatesReceived 30 July 2003; published 10 May 2004 We present a theoretical analysis of the experimental scheme for creating maximally entangled states of many atoms in spin-1 Bose-Einstein condensates by driving single atom Raman transition [ Li You Phys. Rev. Lett. 90 030402 (2003)]. It is shown that, with the help of strong external laser pulses, the model proposed by You can be greatly simplified. Using this simplified interaction, an analytical expression is given for the entangled states between atoms with hyperfine spin −1 and 1. We also show how to generate the entangled state between atoms with hyperfine spin 0 and 1. © 2004 The American Physical Society URL:
