摘要:
光学腔体是控制光-物质相互作用的基础技术。尽管将单个腔体连接到原子或集体体已经成为标准工具,但单个原子在大原子阵列中的控制能力的出现,催生了新的前沿领域,即“多腔量子电动力学(QED)”,该领域具有许多独立的谐振器,能够分别地对单个量子发射体进行定位。在这一快速发展的领域中,腔体阵列显微镜最近被引入——利用自由空间腔内光学来设计一个二维紧密排列的腔体TEM₀₀模式阵列,具有波长尺度的腰部,非常适合与原子阵列对接。在这里,我们实现了这种架构的下一代版本,实现了数百个退化腔体模式,具有改进且均匀的精细度,并探索了该系统的技术特性,这些特性将有助于进一步的可扩展性。特别是,我们研究了各种缺陷,包括光学像差、视场限制、阵列非退化性和光学元件的损耗。我们识别了对这些各种向量的敏感性,并阐述了对齐和操作该系统所需的控制开关和技术。最终,我们提出了一个通往与现有原子阵列兼容的成千上万个独立腔体的操作路径,为多种应用铺平道路,包括高度并行的远程纠缠生成、快速且非破坏性的中电路读取,以及混合原子-光子哈密顿量的实现。
英文摘要:
Optical cavities are a foundational technology for controlling light-matter interactions. While interfacing a single cavity to either an atom or ensemble has become a standard tool, the advent of single atom control in large atomic arrays has spurred interest in a new frontier of ``many-cavity QED,'' featuring many independent resonators capable of separately addressing individual quantum emitters. In this fast-evolving landscape, the cavity array microscope was recently introduced -- employing free space intra-cavity optics to engineer a two-dimensional array of tightly spaced cavity TEM$_{00}$ modes with wavelength-scale waists, ideally suited for interfacing with atom arrays. Here we realize the next-generation of this architecture, achieving hundreds of degenerate cavity modes with improved, uniform finesse, and explore the technical features of the system which will enable further scalability. In particular, we study imperfections, including optical aberrations, field of view constraints, array non-degeneracies, and losses from optical elements. We identify the sensitivity to these various vectors and exposit the control knobs and techniques necessary to align and operate the system in a stable manner. Ultimately, we lay out a pathway towards operation with tens of thousands of independent cavities while maintaining compatibility with existing atom arrays, paving the way to myriad applications including highly parallelized remote entanglement generation, fast and non-destructive mid-circuit readout, and the implementation of hybrid atom-photon Hamiltonians.
