The Greenberger–Horne–Zeilinger (GHZ) state is a specific type of entangled quantum state that involves multiple particles, typically three or more. Named after Daniel Greenberger, Michael A. Horne, and Anton Zeilinger, this state serves as an important example in quantum mechanics, particularly in discussions of entanglement, non-locality, and the foundations of quantum theory.
