GreenbergerHorneZeilinger
The Greenberger-Horne-Zeilinger (GHZ) state is a specific type of entangled quantum state involving three or more particles. It is named after the physicists Daniel Greenberger, Michael Horne, and Anton Zeilinger, who first described it in 1989. GHZ states are crucial in quantum information theory and fundamental tests of quantum mechanics.
A key characteristic of GHZ states is their strong non-classical correlations. For a three-particle GHZ state,
GHZ states provide a stark demonstration of the non-locality predicted by quantum mechanics, contrasting sharply with
