参数耦合超导量子线路的拓扑光子学

Topological photonics on superconducting quantum circuits with parametric couplings

Zheng-Yuan Xue, Yong Hu

摘要:

物质的拓扑相是现代凝聚态物理中的一个奇异现象,由于其独特的边界态和输运性质而引起了人们的广泛关注。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。受设计和控制光学、微波和声音频率的电磁波的行为的启发,拓扑光子学成为一个快速发展的研究领域。由于超导量子线路系统的灵活性和多样性,它为实现物质的奇异拓扑相和探索拓扑保护效应提供了一个很有前途的平台。本文综述了拓扑光子学在超导量子线路中的理论和实验进展,包括超导传输线谐振器、超导量子比特以及它们之间的耦合系统的应用。在超导电路中,灵活的相互作用和固有的非线性使得该系统中的拓扑光子学不仅是新颖器件的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。

英文摘要:

Topological phases of matter is an exotic phenomena in modern condense 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 an promising platform to realize exotic topological phases of matter and to probe and explore topologically-protected effects in new ways. Here, we review 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 the coupled system of them. On superconducting circuits, the flexible interactions and intrinsic nonlinearity making 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.
