三量子比特Gisin定理的完全证明

Complete proof of Gisin's theorem for three qubits

Sujit K. Choudhary, Sibasish Ghosh, Guruprasad Kar, Ramij Rahaman

摘要:

Gisin定理证明了对于任意纯二体纠缠态,存在Bell-CHSH不等式的破坏,揭示了它与局域实在模型的矛盾。类似的结果是否适用于三量子比特纯纠缠态,仍然没有解决。我们分析表明,所有的三量子比特纯纠缠态违反贝尔型不等式,来自本地现实主义的基础上,利用哈代的非定域性参数。

英文摘要:

Gisin's theorem assures that for any pure bipartite entangled state, there is violation of Bell-CHSH inequality revealing its contradiction with local realistic model. Whether, similar result holds for three-qubit pure entangled states, remained unresolved. We show analytically that all three-qubit pure entangled states violate a Bell-type inequality, derived on the basis of local realism, by exploiting the Hardy's non-locality argument.
