Description of Research |
|
Summary Statement of Research Interests |
|
| Our research focuses on the quantum physics of spin systems. Nitrogen-vacancy (NV) impurity centers in diamond are well-isolated from their surrounding environment. NV centers exhibit long quantum coherence which allows us to observe quantum mechanics in the system. We utilize various magnetic resonance techniques to implement quantum gate operations in the NV centers to realize quantum-assisted applications such as an extremely sensitive magnetic sensor which enables imaging of a single electron and nuclear spin. We also apply electron spin magnetic resonance to image static and dynamic structure of biological molecules. | |
