Greenberger–Horne–Zeilinger-state analyzer based on cavity QED
Wei Song, Zhuo‐Liang Cao · Journal of Modern Optics · 2008
We present a N-particle Greenberger–Horne–Zeilinger (GHZ) analyzer in the context of cavity QED. All of the N-particle GHZ states can be discriminated with probability 1 in one step. We also present an application of our scheme in multiparticle entanglement swapping.
