Greenberger–Horne–Zeilinger state
In physics, in the area of quantum information theory, a Greenberger–Horne–Zeilinger (GHZ) state is an entangled quantum state that involves at least three subsystems.

Multipartite generalization of Bell states
The GHZ state extends the concept of entanglement found in two-qubit Bell states to three or more qubits, demonstrating stronger forms of non-locality.
multipartite generalization of entangled states
The GHZ state extends the concept of entanglement to three or more particles, demonstrating non-local correlations that are stronger than those of two-particle systems.
