WebJun 13, 2014 · Entanglement and nonlocality are known to be inequivalent quantum resources. In principle, a generic many-body state—say, a ground state of a local Hamiltonian—is pure, entangled, and because all pure entangled states violate a Bell inequality ( 16 ), also nonlocal. WebOct 12, 2024 · The multipartite correlations derived from local measurements on some composite quantum systems are inconsistent with those reproduced classically. This inconsistency is known as the quantum nonlocality and shows a milestone in the foundations of quantum theory.
