完全相关的Mermin不等式

Mermin inequalities for perfect correlations

Adan Cabello, Otfried Gühne, David Rodriguez

摘要:

任何具有n个独立完美关联的n量子比特态都等价于一个图形态。我们给出了n < 7量子比特的所有图态的最佳贝尔不等式,它们满足完美相关和最大破坏。其中12个是以前未知的,4个给出了与格林伯格-霍恩-蔡林格态相同的破坏,尽管相应的态对退相干更有抵抗力。

英文摘要:

Any n-qubit state with n independent perfect correlations is equivalent to a graph state. We present the optimal Bell inequalities for perfect correlations and maximal violation for all classes of graph states with n < 7 qubits. Twelve of them were previously unknown and four give the same violation as the Greenberger-Horne-Zeilinger state, although the corresponding states are more resistant to decoherence.
