论文摘要
波粒二元性无疑是当代物理学中最奇怪的概念之一，它将相互排斥的行为归因于无法同时观察到的量子系统。在两路干涉仪的背景下，这两种行为通常是用干扰条纹的可见性和路径区分性来描述的。在这里，我们使用量子信息理论工具来得出这两种属性的量词，这解释了路径概率和极化的综合影响，并证明它们满足了互补关系。我们进一步表明，通过揭示有趣的环境动作方面，例如：反熔，去极化和散射，派生的数量可以作为探针的探针起作用。
Wave-particle duality is certainly one of the most curious concepts of contemporary physics, which ascribes mutually exclusive behaviors to quantum systems that cannot be observed simultaneously. In the context of two-path interferometers, these two behaviors are usually described in terms of the visibility of interference fringes and the path distinguishability. Here, we use quantum information-theoretic tools to derive quantifiers of these two properties, which account for the combined influence of path probability and polarization, and demonstrate that they satisfy a complementarity relation. We further show that the derived quantities can work as probes in the study of open quantum dynamics by revealing interesting facets of environment actions, such as: decoherence, depolarization and scattering.
