Quantum Zeno subspace and entangled Bose-Einstein condensates
arXiv:cond-mat/0310638 · doi:10.1103/PhysRevLett.91.230404
Abstract
We discuss a proposal for the efficient generation of the maximally entangled atomic N-GHZ state in a spinor-1 condensate by driving internal state atomic Raman transitions using (classical) laser fields. We illustrate the dynamics in terms of a quantum Zeno subspace, and identify the resultant atomic elastic collision in facilitating the deterministic entanglement creation. Our proposal can be readily implemented in several laboratories where ferromagnetic spinor condensates (of Rb atoms) are investigated.
