摘要单量子发射体之间的辐射场介导耦合所产生的合作现象在片上光子量子存储器和长程纠缠等方面的应用中引起了广泛的兴趣。这些应用的共同点是在宏观距离上产生电磁模式。然而，在这种系统以实际设备的形式部署之前，还需要进行大量的研究，首先是对替代物理平台的研究。二维（2D）系统中的量子发射器提供了一种有趣的途径，因为这些材料可以适应于任意形状的衬底以形成混合系统，其中发射器近场耦合到合适的光学模式。在这里，我们报告了一个可扩展的耦合方法，允许色心合奏的货车范德华材料（六方氮化硼）耦合到离域的高品质的等离子体表面晶格共振。这种类型的架构对于光子应用是有希望的，特别是考虑到六方氮化硼发射器在室温下作为单光子源操作的能力。
Abstract The cooperative phenomena stemming from the radiation field-mediated coupling between individual quantum emitters are presently attracting broad interest for applications related to on-chip photonic quantum memories and long-range entanglement. Common to these applications is the generation of electro-magnetic modes over macroscopic distances. Much research, however, is still needed before such systems can be deployed in the form of practical devices, starting with the investigation of alternate physical platforms. Quantum emitters in two-dimensional (2D) systems provide an intriguing route because these materials can be adapted to arbitrarily shaped substrates to form hybrid systems wherein emitters are near-field-coupled to suitable optical modes. Here, we report a scalable coupling method allowing color center ensembles in a van der Waals material (hexagonal boron nitride) to couple to a delocalized high-quality plasmonic surface lattice resonance. This type of architecture is promising for photonic applications, especially given the ability of the hexagonal boron nitride emitters to operate as single-photon sources at room temperature.
