Realizing highly integrated quantum photonic devices on a chip can enable new opportunities for photonic quantum computation. In this project, we explore heterostructures of stacked two-dimensional (2D) materials, such transition metal dichalcogenides (TMDC) or graphene, combined with optical microcavities as a platform for such devices. 2D materials are extremely thin and flexible, and have emerged as a host for a range of exciting new quantum phenomena, in particular when different 2D materials are stacked together. We plan to address the challenges of stacking more than two layers of 2D materials and of extending the stacking methods to produce wafer-scale structures, as well as the challenges of making this platform compatible by with CMOS infrastructure for future integration towards large-scale quantum photonic computation and networks. We will achieve our goal through an interdisciplinary effort involving deep physical and chemical knowledge, state-of-the-art nanofabrication processing techniques and facilities, extensive material and device characterization measurements, and theoretical investigations.
Topological Properties of Exciton-Polaritons in a Kagome Lattice as a Solid-state Quantum Simulator
Summary In this project, we build a solid-state quantum simulator for engineering a specific Hamiltonian. Quantum simulators are purpose-built devices with little to no need for error correction, thereby making this type of hardware less demanding than universal quantum computers. Our platform consists of exciton-polariton condensates in multiple quantum-wells sandwiched in a semiconductor Bragg […]

Quantum Dynamics of Cavity Interactions with Spin Ensembles
Summary High quality factor cavities can be powerful control elements for ensembles of spins, enabling unitary control as well as on demand cooling. They can also be used to couple two otherwise non-interacting ensembles. The goal of the project is to explore the physics and engineering of such systems both theoretically and experimentally. The laboratory contains a […]
