我们描述了一个超导电路晶格设计的实施和模拟的动态格点规范理论。我们通过分析一维U（1）量子链模型来说明我们的建议，其中超导量子比特在晶格位置上扮演物质场的角色，规范场由相邻位置之间的每个链接上的两个耦合微波谐振器表示。一个最小的实验协议的详细分析，用于探测与字符串断裂效应相关的物理表明，尽管存在退相干在这些系统中，独特的现象，从凝聚态物质和高能物理可以可视化与国家的最先进的技术在小型超导电路阵列。
We describe a superconducting-circuit lattice design for the implementation and simulation of dynamical lattice gauge theories. We illustrate our proposal by analyzing a one-dimensional U(1) quantum-link model, where superconducting qubits play the role of matter fields on the lattice sites and the gauge fields are represented by two coupled microwave resonators on each link between neighboring sites. A detailed analysis of a minimal experimental protocol for probing the physics related to string breaking effects shows that, despite the presence of decoherence in these systems, distinctive phenomena from condensed-matter and high-energy physics can be visualized with state-of-the-art technology in small superconducting-circuit arrays.
