Next generation quantum light sources based on 2D materials

拟议的计划将连接两个具有重要战略意义的研究领域-量子材料和量子信息。通过构建由二维（2D）量子材料（氮化硼、石墨烯、二硒化钨等）组成的新型异质结构器件，例如透明电容器、p-i-n结和微柱腔，可以利用它们的独特性质来实现用于量子信息的片上可调谐单光子源。这样的源不仅形成涉及光子的许多量子通信和信息处理架构的整体组件（例如，量子密钥分配、量子中继器和线性光学量子计算），它们还可以用于解析超出衍射极限的特征，在量子成像和光刻中找到应用。因此，它们的发展，特别是在可扩展平台上的发展，对于推动一系列量子技术走向广泛的商业用途是必要的。

The proposed program shall interface two strategically important research areas – quantum materials and quantum information. By building novel heterostructure devices, such as transparent capacitors, p-i-n junctions, and micropillar cavities, consisting of two-dimensional (2D) quantum materials (boron nitride, graphene, tungsten diselenide, etc.), their unique properties can be exploited to realize on-chip, tunable single photon sources for quantum information. Such sources not only form integral components of many quantum communication and information processing architectures involving photons (e.g., quantum key distribution, quantum repeaters, and linear optics quantum computing), they can also be used to resolve features beyond the diffraction limit, finding applications in quantum imaging and lithography. Their development, especially in scalable platforms, is thus necessary to push forward a range of quantum technologies towards widespread commercial usage.
