    Summary 

    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.

    Spin-transfer Torque Magnetic Random Access Memory for On-chip Spin Information Storage

    Summary   Leakage power in semiconductor memories, such as Dynamic Random Access Memory (DRAM) and Static Random Access Memory (SRAM), can be substantial and is one of the limits for scalability of classical electronics. This is attributed to the fact that the information stored is volatile, requiring constant refreshing, as well as reprogramming upon powering […]

    Rydberg Atom Array Quantum Simulator

    Summary  Quantum simulators enable probing the static and dynamic properties of correlated quantum many-body systems that would otherwise be numerically inaccessible using classical simulators. We are developing quantum simulators based on arrays of neutral atoms excited to Rydberg states. Such Rydberg atom arrays are advantageous for simulating the dynamics of interacting spin systems (Ising spin […]

    Quantum Simulations of Fundamental Interactions

    Summary To address questions in modern physics such as “what is the structure of matter inside neutron stars?” we need better computational methods to evaluate the interplay of fundamental forces between elementary particles. To-date the response to such questions rests on numerical computer simulations that are inherently limited. In this project, we develop new theoretical […]
