WebThe Greenberger, Horn, Zeilinger (GHZ) theorem [1] has achieved a status similar to that of Bell’s theorem in its acceptance as a proof that local hidden variables are im- possible in quantum mechanics. It has a similarity to Bell’s theorem in that it considers a mathematical rela- tion among predicted results of alternative measurements
