Realization of atomic Greenberger—Horne—Zeilinger states via cavity quantum electrodynamics
E. S. Guerra, J. C. Retamal · Journal of Modern Optics · 1999
In this work we propose a scheme in which it is possible to generate atomic Greenberger—Horner—Zeilinger (GHZ) states by letting three-level atoms in a lambda configuration interact with a cavity field followed by a displacement of the cavity field and selective measurements on two-level atoms which disentangle the atoms and field states. We also propose a GHZ test based on such states.
