物质的拓扑相是现代凝聚态物理中的一种奇异现象，由于其独特的边界态和输运性质而引起人们的广泛关注。最近，电子材料中的这种拓扑概念已被应用于物理学的许多其他领域。受设计和控制光、微波和声频电磁波行为的启发，拓扑光子学成为一个快速发展的研究领域。由于超导量子电路系统的灵活性和多样性，它是一个很有前途的平台，实现奇异的拓扑相的物质和探测和探索拓扑保护效应的新方法。本文综述了超导量子电路拓扑光子学的理论和实验研究进展，包括超导传输线谐振器、超导量子比特及其耦合系统的应用。在超导电路上，灵活的相互作用和固有的非线性使该系统中的拓扑光子学不仅是新颖器件拓扑效应的简单光子模拟，而且还是一个奇异但较少探索的基础物理领域。
Topological phases of matter are an exotic phenomenon in modern condensed matter physics, which has attracted much attention due to the unique boundary states and transport properties. Recently, this topological concept in electronic materials has been exploited in many other fields of physics. Motivated by designing and controlling the behavior of electromagnetic waves in optical, microwave, and sound frequencies, topological photonics emerges as a rapid growing research field. Due to the flexibility and diversity of superconducting quantum circuits system, it is a promising platform to realize exotic topological phases of matter and to probe and explore topologically‐protected effects in new ways. Here, theoretical and experimental advances of topological photonics on superconducting quantum circuits—via the experimentally demonstrated parametric tunable coupling techniques, including using of the superconducting transmission line resonator, superconducting qubits, and their coupled system—are reviewed. On superconducting circuits, the flexible interactions and intrinsic nonlinearity make topological photonics in this system not only a simple photonic analog of topological effects for novel devices, but also a realm of exotic but less‐explored fundamental physics.
