Negatively charged NV center has long been considered as a promising candidate for nanoscale sensing and quantum information. In each defect, a nitrogen atom and an adjacent vacancy substitute for two carbon atoms in diamond lattice. NV center has a spin striplet electronic state, that can be optically polarized, detected, and coherently manipulated. In this talk, I will introduce our effort of (1) using shallow implanted single NV center as a local magnetometry in studying the magnetic properties of layered 2D material, (2) using NV ensemble to study and image the strain distribution in diamond anvil cell system, and (3) using dense NV ensemble and nearby nitrogen impurities (P1 centers) as a quantum simulator for many-body spin system.
Chong Zu is currently a postdoc scholar at University of California, Berkeley where he works on nanoscale ultrasensitive magnetometry based on NV center in diamond. He received his Doctoral degree in physics from Center for Quantum Information, IIIS, Tsinghua University, in 2016, under the supervision by Prof. Luming Duan. His doctoral thesis mainly focuses on experimental quantum information processing (QIP) with entangled photons and nitrogen-vacancy (NV) center in diamond. Prior to his Ph.D., he received his Bachelor's degree from Department of Physics, Tsinghua Uniersity, in 2011.
