EPR实验中的时间、"意外"和其他人为现象
Timing, ``Accidentals'' and Other Artifacts in EPR Experiments
摘要:
在爱因斯坦-波多尔斯基-罗森实验中,减去“偶然事件”经常会把与局部实在论相容的结果变成似乎证明非局部性的结果。该程序的有效性取决于未经证实的假设排放事件的独立性。其他可能的偏差来源包括增强,不完美的同步,过度依赖旋转不变性,以及众所周知的检测漏洞。对现有结果的研究可能比尝试无环孔贝尔测试更有成效,从而提高我们对光的理解。
英文摘要:
Subtraction of ``accidentals'' in Einstein-Podolsky-Rosen experiments frequently changes results compatible with local realism into ones that appear to demonstrate non-locality. The validity of the procedure depends on the unproven assumption of the independence of emission events. Other possible sources of bias include enhancement, imperfect synchronisation, over-reliance on rotational invariance, and the well-known detection loophole. Investigation of existing results may be more fruitful than attempts at loophole-free Bell tests, improving our understanding of light.
