Recent progresses on quantum sensing based on nitrogen vacancy center in diamond

Abstract:

Nitrogen vacancy (NV) center in diamond has been widely used in various quantum applications, including quantum communications, quantum computing and quantum sensing. since NV center is sensitive to various physical parameters, it has been used to measure magnetic, electrical, mechanical and thermal effects. In this talk, we will present recent progresses made in our team on quantum sensing applications, including creating and optimizing NV centers in bulk and shallow implanted forms, sensing phase transitions driven by pressure and novel quantum signal filters based on its quantum nature.

Dr. Sen Yang received his Bachelor's degree in Physics at Tsinghua University in Beijing (2002), and Ph.D. in Physics at the University of California, San Diego (2009). He did Postdoc researches in University of Texas at Austin and University of Stuttgart. From 2016-2021, he was an assistant professor in the department of physics in the Chinese University of Hong Kong. Since 2021, he works as an associate professor in the department of physics at the Hong Kong University of Science and Technology. His research interest is solid state optics and quantum optics based on solid state qubits, and in particular developing quantum information technologies with color centers such as nitrogen vacancy centers in diamond. The group has been working on using those qubits to sense quantum physics in various systems, as well as building quantum information devices. They are also developing novel direct laser writing fabrication technologies.
