Research

Our research group focuses on developing quantum sensing and imaging technique to study various properties (spin, charge, and heat, etc) of quantum materials in the nanometer scale. In addition, we design and engineer hybrid quantum devices to achieve efficient qubit control for quantum information applications. Our research tools are versatile, including optical measurement based on nitrogen vacancy center in diamond, transport and microwave spectroscopy as well as scanning probe magnetometry.
