Challenges and opportunities for quantum light sources based on 2D materials

On-demand generation of single photons with solid-state emitters is a major technological challenge for a wide range of quantum information science technologies. The ideal system not only produces high rates of indistinguishable single photons but is also sufficiently versatile to be integrated with a wide range of quantum photonic systems. Single atomic layers of 2D semiconductors such as WSe2 can generate quantum states of light and promise nearly limitless versatility for such heterogeneous integration. However, optimization of their performance as emitters has been hampered by an insufficient understanding of the structure-property relationships that govern their formation and behavior. In this talk, I will discuss our work to uncover these relationships and optimize emitter properties via nanoscale engineering of the 2D semiconductor system. I will also preview our current efforts to integrate these systems into prototype quantum networks and develop advanced manufacturing tools for quantum components based on 2D materials as part of the 2D Quantum Materials Pipelines of the MonArk NSF Quantum Foundry.
