论文摘要
波粒二元关系对于量子物理学是基本的。对二元关系的先前实验研究主要集中在二次关系上$ d^2+v^2 \ leq1 $，基于对称光束干扰，而二元关系的线性形式在理论上从未经过实验测试。另外，尚未探索二次形式和线性形式之间的差异。在这项工作中，使用设计的不对称束干扰并利用光子的极化度作为A向检测器的极化程度，我们通过实验确认了两种形式的偶性关系。结果表明，在二次情况下获得了更多路径信息。我们的发现揭示了两个二元关系之间的区别，并在更好地理解这些重要的二元关系方面具有根本的含义。
Wave-particle duality relations are fundamental for quantum physics. Previous experimental studies of duality relations mainly focus on the quadratic relation $D^2+V^2\leq1$, based on symmetric beam interference, while a linear form of the duality relation, predicated earlier theoretically, has never been experimentally tested. In addition, the difference between the quadratic form and the linear form has not been explored yet. In this work, with a designed asymmetric beam interference and by utilizing the polarization degree of freedom of the photon as a which-way detector, we experimentally confirm both forms of the duality relations. The results show that more path information is obtained in the quadratic case. Our findings reveal the difference between the two duality relations and have fundamental implications in better understanding these important duality relations.
