Nanoscale Quantum Sensing

Our Group

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. Here is a video on our lab.

Openings

We are recruiting at all levels. We are looking for motivated postdocs with experience on 2D devices and/or scanning probe microscopy. If you are interested, please email (cdu71[at]gatech.edu) to discuss research opportunities.
