对“3-qubit GHZ类态中的三体纠缠与三体非定域性”一文的评论

A comment on "Tripartite entanglement versus tripartite nonlocality in 3-qubit GHZ-class states"

Vibhu Gupta

摘要:

题为“三重纠缠与三重非定域性在3-qubit GHZ类状态”的论文(Physical Review Letters 102,250404(2009))在研究Svetlichny不等式(Bell型不等式)的性质方面做了非常重要的工作,并揭示了Svetlichny不等式和三重纠缠之间的一些重要性质和关系。导出了GGHZ态和MS态Svetlichny算符的最大期望值。本文指出,本文所导出的中心结果可能存在错误。

英文摘要:

The paper titled "Tripartite entanglement versus tripartite nonlocality in 3-qubit GHZ-class states", (Physical Review Letters 102, 250404 (2009)), does very important work on studying the nature of Svetlichny Inequalities (which are Bell-type inequalities) and sheds light on some important properties and relationship between Svetlichny inequality and tripartite entanglement. It derives a result for the maximum expectation value of Svetlichny operator for GGHZ and MS states. In this comment, it is put forth that there is probably a mistake in the central result derived in the paper.
