EPRB实验中的光子识别漏洞:单翼选择的计算机模型
The photon identification loophole in EPRB experiments: computer models with single-wing selection
摘要:
最近的爱因斯坦-波多尔斯基-罗森-玻姆实验[M. Giustina等人,Phys. Rev. Lett. 115,250401(2015); L. K. Shalm等人,Phys. Rev. Lett. 115,250402(2015)],并被证明存在光子识别漏洞。数字计算机和离散事件模拟的组合用于构建这些实验室实验的最完美实现的最小但忠实的模型。与先前的模拟相反,所有光子的选择都是严格进行的,就像在实际实验中一样,在本地站进行,不涉及其他“后选择”。模拟结果表明,一个明显的非量子模型,识别光子在相同的本地方式,在这些实验中可以产生的相关性,是在良好的协议与量子理论描述的相应的思想实验,在冲突与贝尔定理。贝尔定理的失败是可能的,因为我们认识到了光子识别的漏洞。这种识别测量程序必然包括在所有实际实验中,但不包括在贝尔及其追随者的理论中。
英文摘要:
Recent Einstein-Podolsky-Rosen-Bohm experiments [M. Giustina et al. Phys. Rev. Lett. 115, 250401 (2015); L. K. Shalm et al. Phys. Rev. Lett. 115, 250402 (2015)] that claim to be loophole free are scrutinized and are shown to suffer a photon identification loophole. The combination of a digital computer and discrete-event simulation is used to construct a minimal but faithful model of the most perfected realization of these laboratory experiments. In contrast to prior simulations, all photon selections are strictly made, as they are in the actual experiments, at the local station and no other "post-selection" is involved. The simulation results demonstrate that a manifestly non-quantum model that identifies photons in the same local manner as in these experiments can produce correlations that are in excellent agreement with those of the quantum theoretical description of the corresponding thought experiment, in conflict with Bell's theorem. The failure of Bell's theorem is possible because of our recognition of the photon identification loophole. Such identification measurement-procedures are necessarily included in all actual experiments but are not included in the theory of Bell and his followers.
