Our lab investigates new quantum sensing techniques and their application to probe physical properties of biological processes with nanoscale resolution. The scientific challenges that we address fall roughly into two distinct yet synergetic areas:
Next Generation Quantum Sensors: What are the sensitivity limits of nanoscale quantum sensors in a noisy environment and can we engineer qubit sensors and sensing protocols that overcome these limitations?
Applications to Biological Targets: How can we interface these qubit sensors with biological systems and what are the specific biological questions that we can address with quantum sensing?
We explore the experimental aspects of these questions by combining techniques from quantum engineering, single-molecule biophysics, and physical chemistry. In the first thrust, we explore both diamond based technology and alternative qubit systems, while in the second thrust we rely primarily on established qubit sensors, notably nitrogen vacancy (NV) centers in diamond. The resulting insights gained from our work will lead to (i) a deeper understanding and improved control of quantum systems in a noisy environment and (ii) establish quantum technology as a new resource for biophysical research and biomedicine.
