基于波和粒子关联的连续变量无漏洞Bell检验

Loophole-free Bell test for continuous variables via wave and particle correlations

Se-Wan Ji, Jaewan Kim, Hai-Woong Lee, M. S. Zubairy, Hyunchul Nha

摘要:

在局域现实假设下,我们得到了两类多模贝尔不等式,根据Peres猜想,这些不等式仅在部分转置下的纠缠态为负时才成立.值得注意的是,局部现实主义的失败可以通过利用容易获得的连续变量状态的波和粒子相关性来表现出来,这极大地违反了对探测器效率不敏感的不等式,这使得无漏洞测试成为一个强有力的理由。

英文摘要:

We derive two classes of multi-mode Bell inequalities under local realistic assumptions, which are violated only by the entangled states negative under partial transposition in accordance with the Peres conjecture. Remarkably, the failure of local realism can be manifested by exploiting wave and particle correlations of readily accessible continuous-variable states, with very large violation of inequalities insensitive to detector-efficiency, which makes a strong case for a loophole-free test.
