论文摘要
我们在实验和理论上研究了分散耦合方案以外的驱动杂种量子电动力学（CQED）系统。将腔当作驱动系统的一部分，我们开发了一种适用于如此强烈的耦合和多量子系统的理论。在存在第二个DQD的情况下，用于单个驱动的双量子点（DQD） - 腔设置和混合浮雕状态的扩大分裂的条纹和模型都很好地再现了混合浮雕状态的扩大。这开辟了一条以任意强耦合来研究多量系统系统的浮标状态的途径，并揭示了一种新的观点，可以理解强烈驱动的混合动力系统。
We experimentally and theoretically study a driven hybrid circuit quantum electrodynamics (cQED) system beyond the dispersive coupling regime. Treating the cavity as part of the driven system, we develop a theory applicable to such strongly coupled and to multi-qubit systems. The fringes measured for a single driven double quantum dot (DQD)-cavity setting and the enlarged splittings of the hybrid Floquet states in the presence of a second DQD are well reproduced with our model. This opens a path to study Floquet states of multi-qubit systems with arbitrarily strong coupling and reveals a new perspective for understanding strongly driven hybrid systems.
