Entanglement and spin squeezing of Bose condensed atoms
arXiv:cond-mat/0212286 · doi:10.1103/PhysRevA.68.043622
Abstract
We propose a direct, coherent coupling scheme that can create massively entangled states of Bose-Einstein condensed atoms. Our idea is based on an effective interaction between two atoms from coherent Raman processes through a (two atom) molecular intermediate state. We compare our scheme with other recent proposals for generation of massive entanglement of Bose condensed atoms. We also present explicit calculations that support detecting maximally entangled states without requiring single atom resolved measurements.
