光子在量子应用中起着至关重要的作用，因为它们能够以不同的自由度对量子信息进行编码并以光速传输。由于光子与物质的相互作用相对较弱，因此光子的量子态对退相干具有特别的鲁棒性。然而，这种弱光-物质相互作用也限制了量子光子操作的速率，如单光子产生或光子-光子相互作用。等离子体超材料可以改善光-物质相互作用，显著加快量子光子过程。在这项工作中，我们概述了我们在应用等离子体增强自发发射以实现高速明亮量子发射器方面的研究工作。最终目标是提高自发发射速率，使其超过无冷冻温度下固态量子发射器的典型脱相速率。这样就可以在不需要低温恒温器的情况下产生难以区分的光子。本文报道了六方氮化硼和氮化硅等适合与等离子体超材料耦合和集成量子光子学的材料平台上的固态量子发射器的工程设计。
Photons play a crucial role in quantum applications due to their ability to encode quantum information in various degrees of freedom and transmit it at the speed of light. The quantum states of photons are exceptionally robust against decoherence since photons interact relatively weakly with matter. However, this weak light-matter interaction also limits the rate of quantum photonic operations such as single photon generation or photon-photon interactions. Plasmonic metamaterials can improve light-matter interaction and dramatically speed up quantum photonic processes. In this work, we give an overview of our research efforts regarding the application of plasmonics for spontaneous emission enhancement to enable high-speed bright quantum emitters. The ultimate goal is to enhance the spontaneous emission rate beyond the dephasing rate typical for solid-state quantum emitters at cryo-free temperatures. This would enable the generation of indistinguishable photons without the need of a cryostat. We report on the engineering of solid-state quantum emitters in material platforms such as hexagonal boron nitride and silicon nitride suitable for coupling with plasmonic metamaterials and integrated quantum photonics.
