Group IV color centers in single crystal diamond membrane for quantum network

ORAL

Abstract

Group IV color centers in single crystal diamond have emerged as promising candidates for realizing long-range quantum optical network, thanks to their coherent optical transitions and controllable spin states. To fully utilize their superb optical and spin properties, it is critical to integrate them with other on-chip optical and electrical structures. Using single crystal diamond membrane, we developed a versatile platform that enables strain tuning and nanophotonic integration. As a result, individual quantum emitters such as silicon vacancy (SiV) and germanium vacancy (GeV) centers, have shown stable optical emissions with high contrasts and narrow linewidths (200-500 MHz). Recent progress related to strain engineering of these color centers will also be discussed.
