摘要: Nonlocality without inequality is an elegant argument introduced by Hardy for two qubit systems, and later generalised to n qubits, establish contradiction of quantum theory with local realism. Interestingly, = 2 this actually a corollary Bell-type inequalities, viz., the CH–Hardy involving Bell correlations, but greater than it involves n-particle probabilities more general Bell-correlations. In paper, we first derive chain completely new realistic inequalities joint qubits then associated each such inequality, provide Hardy-type reality constraint inequalities. Quantum mechanical maximal violations constraints are also studied deriving appropriate Cirel'son-type theorems. These results correlations expected systematic tool investigate entanglement.
