Next generation quantum light sources based on 2D materials

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.
