Photonic de Broglie waves offer a unique property of quantum mechanics satisfying the complementarity between the particle and wave natures of light, where the photonic de Broglie wavelength is inversely proportional to the number of entangled photons acting on a beam splitter. Very recently, the nonclassical feature of photon bunching has been newly interpreted using the pure wave nature of coherence optics [Sci. Rep. 10, 7,309 (2020)], paving the road to unconditionally secured classical key distribution [Sci. Rep. 10, 11,687 (2020)]. Here, deterministic photonic de Broglie waves are presented in a coherence regime to uncover new insights in both fundamental quantum physics and potential applications of coherence-quantum metrology.
光子德布罗意波具有量子力学的独特性质，满足光的粒子性与波动性之间的互补性，其中光子德布罗意波长与作用在分束器上的纠缠光子数成反比。最近，利用相干光学的纯波动性质对光子聚束的非经典特性进行了新的诠释[《科学报告》10, 7309 (2020)]，为无条件安全的经典密钥分发铺平了道路[《科学报告》10, 11687 (2020)]。在此，确定性光子德布罗意波出现在一个相干区域，以揭示基础量子物理学和相干量子计量潜在应用方面的新见解。
