超导量子电路以约瑟夫森结的非线性电感为核心，将微纳加工的人造电路构造成可量子化、可设计、可操控的“人工原子”，是当前实现通用量子计算最具竞争力的物理体系之一。在这一体系中，量子比特、可调耦合器、微波谐振腔和传输线共同构成了片上量子电动力学系统。通过外加微波场和磁通偏置，可以在纳秒量级精确调控量子态的相干演化、能级结构、相互作用强度以及多体哈密顿量，从而为研究光与物质相互作用、开放量子系统动力学、多体量子物理以及量子纠错等基本物理问题提供了高度可控的平台。
课题组长期面向可扩展超导量子计算开展研究，致力于理解和调控人工量子体系中的相干性、耦合与多体动力学。我们从约瑟夫森结、超导材料与芯片结构中的微观耗散机制出发，研究量子噪声和退相干的物理起源；通过可调耦合与多比特哈密顿量工程，探索量子态传输、远程纠缠生成和可编程量子动力学；并进一步将这些物理机制应用于量子信息处理、量子算法演示和量子纠错实验，为构建大规模容错超导量子处理器奠定基础。
未来研究将进一步以实现可扩展、可容错的超导量子计算为目标，依托现有的成熟微纳加工平台、高性能低温和室温量子测控系统，重点开展以下方向的研究：
