Franson-type nonlocal correlation is related to Bell inequality violation tests and has been applied for quantum key distributions based on time bin methods. Using unbalanced Mach-Zehnder interferometers, Franson correlation measurements result in an interference fringe, while local measurements do not. Here, randomness-based macroscopic Franson-type correlation is presented using polarization-based two-mode coherent photons, where the quantum correlation is tested by a Hong-Ou-Mandel scheme. Coherent photons are used to investigate the wave properties of this correlation. Without contradicting the wave-particle duality of quantum mechanics, the proposed method provides fundamental understanding of the quantum nature and opens the door to deterministic quantum information science.
弗兰森型非局域关联与贝尔不等式违背测试相关，并已应用于基于时间间隔方法的量子密钥分发。使用非平衡马赫-曾德尔干涉仪，弗兰森关联测量会产生干涉条纹，而局域测量则不会。在此，利用基于偏振的双模相干光子提出了基于随机性的宏观弗兰森型关联，其中量子关联通过洪-欧-曼德尔方案进行测试。相干光子用于研究这种关联的波动特性。在不与量子力学的波粒二象性相矛盾的情况下，所提出的方法提供了对量子本质的基本理解，并为确定性量子信息科学打开了大门。
