Greenberger-Horne-Zeilinger nonlocality in arbitrary even dimensions
Jinhyoung Lee, Seung-Woo Lee, M. S. Kim · Physical Review A · 2006
We generalize Greenberger-Horne-Zeilinger (GHZ) nonlocality to every even-dimensional and odd-partite system. For the purpose we employ concurrent observables that are incompatible and nevertheless have a common eigenstate. It is remarkable that a tripartite system can exhibit the genuinely high-dimensional GHZ nonlocality.
