Quantum Sensors with Diamonds: Utilizing the Flaws of Nature
Dr. Sorawis Sangtawesin Princeton University, US
Date: Saturday 9th March 2019, 21:00-22:30 GMT+7
This is an introduction on using quantum systems as sensors. These sensors can utilize quantum mechanical properties to enhance their performance for detecting classical, real world signals. Moreover, they allow access to an unprecedented regime where a single molecule or even a single electron can be detected, and their nanoscale dynamics can be observed. The talk will begin with a discussion of general sensing applications and a brief overview of how quantum mechanics can be utilized for sensing. Then, we will look at a few examples of quantum sensor platforms before focusing on the topic of using defects in diamond as a quantum system and quantum sensor.
About the speaker:
Sorawis Sangtawesin received his Ph.D. working with Prof. Jason Petta at Princeton University Department of Physics, where his research focused on using the nitrogen-vacancy (NV) defect centers as a building block for quantum computing. He is currently a postdoctoral research associate in Prof. Nathalie de Leon’s lab at Princeton University Department of Electrical Engineering, where he is working on using surface science methods to improve the coherence time of shallow NV centers for quantum sensing applications.
