Abstract

This work aims to advance the room-temperature manipulation of photonic qubits and enhance coherence preservation in and for quantum applications via tailored spatio-spectral localized (SSL) systems. We focus on an innovative all-plasmonic SSL system consisting of a gold bowtie array on a gold substrate. This design produces a high-Q spectral-localized mode through the lattice array, emerging from the collective lattice response of localized surface plasmon resonance (LSPR), particularly the surface lattice resonance (SLR). The SSL system enables tunable modal coupling between the LSPR and SLR, allowing precise alignment with quantum emitters to form quasi-bound states across an energy range of 1.45–1.91 eV. This flexibility allows us to investigate how innovative configurations – such as three-body coupling symmetry and modal-coupling strength – affect coherence protection. These insights pave the way for optimizing SSL systems, setting the stage for significant advancements in nanophotonic qubit manipulation at ambient conditions and the future of photonic quantum systems.

用于室温量子相干保护的空间光谱局域模态耦合

这项工作旨在推进光子量子比特的室温操作，并通过定制的空间光谱局域化（SSL）系统增强量子应用中的相干性保存。我们专注于一种创新的全等离子体SSL系统，该系统由金衬底上的金领结阵列组成。该设计通过晶格阵列产生高q谱局域模式，产生于局域表面等离子体共振（LSPR）的集体晶格响应，特别是表面晶格共振（SLR）。SSL系统可以在LSPR和SLR之间实现可调谐的模态耦合，允许与量子发射器精确对齐，在1.45-1.91 eV的能量范围内形成准束缚态。这种灵活性使我们能够研究创新结构（如三体耦合对称性和模态耦合强度）如何影响相干保护。这些见解为优化SSL系统铺平了道路，为在环境条件下纳米光子量子比特操作和光子量子系统的未来取得重大进展奠定了基础。
