摘要:

我们应用一种基于距离的Bell检验分析方法[E. Knill等人,物理学修订版A。91,032105(2015)]到三个实验数据集,其中常规分析失败或需要额外的假设。第一个是从一个新的经典来源利用“巧合时间漏洞”,标准分析错误地显示贝尔违反。第二个是从一个源先前被证明违反了贝尔不等式,基于距离的分析同意与以前的结果,但较少的假设。第三个数据集没有显示出违反标准分析,尽管高源质量,但显示出具有强烈的违反与基于距离的分析方法。

英文摘要:

We apply a distance-based Bell-test analysis method [E. Knill et al., Phys. Rev. A. 91, 032105 (2015)] to three experimental data sets where conventional analyses failed or required additional assumptions. The first is produced from a new classical source exploiting a "coincidence-time loophole" for which standard analysis falsely shows a Bell violation. The second is from a source previously shown to violate a Bell inequality; the distance-based analysis agrees with the previous results but with fewer assumptions. The third data set does not show a violation with standard analysis despite the high source quality, but is shown to have a strong violation with the distance-based analysis method.
