论文摘要
光子de Broglie波（PBWS）通过两种模式纠缠的光子对相互作用在梁分离器上显示出纯量子特征，该特征无法通过经典的平均值1-4获得。尽管在过去的几十年中，对PBW进行了深入研究量子计量学5-13和Quantum Sensing14-25，但由于高阶中午国家一代的困难，它们的实现受到限制。最近，在不对称耦合的Mach-Zehnder干涉仪（MZI）26中提出了一个连贯的PBWS，即所谓的Cooherence de Broglie波（CBW）。与PBW不同，CBW的量子性源自耦合MZI的级联量子叠加。在这里，第一个CBWS观察列出了纯经典制度，并讨论了其在相干量子计量学中的潜在应用，以克服受高阶纠缠光子限制的常规PBW。为了理解CBW中基于量子叠加的非分类特征，还进行了各种违规测试，其中不对称相位耦合是CBW的关键参数。
Photonic de Broglie waves (PBWs) via two-mode entangled photon pair interactions on a beam splitter show a pure quantum feature which cannot be obtained by classical means1-4. Although PBWs have been intensively studied for quantum metrology5-13 and quantum sensing14-25 over the last several decades, their implementation has been limited due to difficulties of high-order NOON state generation4. Recently a coherence version of PBWs, the so-called coherence de Broglie waves (CBWs), has been proposed in a pure classical regime of an asymmetrically coupled Mach-Zehnder interferometer (MZI)26. Unlike PBWs, the quantumness of CBWs originates from the cascaded quantum superposition of the coupled MZI. Here, the first CBWs observation is presented in a pure classical regime and discussed for its potential applications in coherence quantum metrology to overcome conventional PBWs limited by higher-order entangled photons. To understand the quantum superposition-based nonclassical features in CBWs, various violation tests are also performed, where asymmetrical phase coupling is the key parameter for CBWs.
