关闭时间一致漏洞的Svetlichny不等式
Svetlichny inequality with closing coincidence-time loophole
摘要
Abstract
In any Bell inequality,existence of loopholes leads to inequality violation may not correspond to a violation of local realism,which threatens the security of quantum information processing task.Coincidence-time loophole,as a major one,is closed in bipartite Bell inequalities.Svetlichny inequality,as a typical multipartite Bell inequality which implies genuine multipartite correlation,suffers from coincidence-time loophole.Therefore,based on tripartite Svetlichny inequality,the conditions of closing coincidence-time loophole is given.Furthermore,the conditions of closing coincidence-time loophole of n(n≥3)partite Svetlichny inequality is given,which shows a more general result.The derived Svetlichny inequality with closing coincidence-time loophole offers a fundamental tool for device-ndependent multipartite quantum information processing protocols.关键词
