AI 中文摘要
自旋系综被视为量子存储和量子增强传感应用的潜在候选。本文探究多个超导微波腔与自旋系综的受控耦合，该耦合呈现强耦合特征，且因多模特性形成暗态。暗态尤为受关注，因其可提供延长存储时间的潜在途径，并能通过抑制与电路环境的耦合，实现自旋系综中非经典态的受保护存储。我们对自旋-多腔混合系统进行建模，以重现光谱并采用输入-输出形式提取特征耦合强度。
英文摘要
Spin ensembles are considered as potential candidates for quantum memory and quantum enhanced sensing applications. Here, we explore the controlled coupling of multiple superconducting microwave cavities to a spin ensemble, which shows signatures of strong coupling and, due to the multi-mode character, the formation of dark states. In particular, the latter are of interest, as they provide a potential pathway to enhance memory times and enable protected storage of non-classical states in spin ensembles due to the suppressed coupling to the circuit environment. We model the spin multi-cavity hybrid to reproduce the spectra and extract characteristic coupling strengths using the input-output formalism.
