Synthesis and characterization of quantum defects for quantum network applications: from deep centers in diamond to shallow impurities in ZnO

University of Washington

Point defects in crystals are the solid state analog to trapped ions. Thus these “quantum defects” have gained popularity as qubit candidates for scalable quantum networks.  In this talk, I will introduce some of the basic quantum defect properties desirable for quantum network applications and give some illustrative examples of recent successes toward scalable quantum networks, highlighting my group’s work on single NV centers in diamond and shallow donors in ZnO. I will also discuss outstanding challenges (or opportunities) toward scaling quantum systems based on defects, which include photon loss and maintaining spin and optical coherence in integrated devices. 

Bio: Kai-Mei is an Associate Professor of Physics and Electrical and Computer Engineering at the University of Washington. Her research focuses on understanding and engineering the quantum properties of point defects in crystals, and utilizing these properties in photonic devices for quantum information and sensing applications. Kai-Mei Fu received her A.B. in Physics from Princeton University in 2000 and Ph.D. in Applied Physics from Stanford University in 2007

We are hosting the Spring 2021 JQI Seminars virtually as Zoom meetings. JQI members and affiliates will receive a Zoom link in an email announcing each seminar. For those without access to Zoom, we will also be live streaming each seminar on YouTube. Once a seminar starts, you will find a link to the live stream on our YouTube page at https://www.youtube.com/user/JQInews.
