摘要

量子相干在量子力学和量子信息处理中发挥着重要作用。它可以被视为一种重要的量子资源。相干的量化是相干理论的核心。几何相干性作为相干性的一种度量，可以有效地量化量子相干性。在这项工作中，我们提出了几何相干性与互不偏倚基的互补关系。然后，基于这些互补关系，我们建立了几何相干性与量子转向之间的关系。

Applications of Geometric Coherence with Respect to Mutually Unbiased Bases

Quantum coherence plays a vital role in quantum mechanics and quantum information processing. It can be regarded as an important quantum resource. Quantification of coherence is the core of coherence theory. Geometric coherence as a measure of coherence can effectively quantify quantum coherence. In this work, we drive complementarity relations for geometric coherence with respect to mutually unbiased bases. Then, based on these complementarity relations, we establish the relationship between geometric coherence and quantum steering.

期刊介绍： International Journal of Theoretical Physics publishes original research and reviews in theoretical physics and neighboring fields. Dedicated to the unification of the latest physics research, this journal seeks to map the direction of future research by original work in traditional physics like general relativity, quantum theory with relativistic quantum field theory,as used in particle physics, and by fresh inquiry into quantum measurement theory, and other similarly fundamental areas, e.g. quantum geometry and quantum logic, etc.
