Quantum optics with silicon-vacancy centers in diamond

POSTER

Abstract

The silicon vacancy is a color center in diamond with spectrally stable and bright optical transitions. We demonstrated two-photon interference from separated SiV centers, measured electronic spin lifetime (2.4ms) and coherence (35ns) via coherent population trapping, and carried out time resolved fluorescence measurements to identify electron-phonon relaxation mechanisms that limit the spin coherence time. Ways to extend spin coherence times and recent experiments where a single SiV center is coupled to a nanophotonic crystal cavity are also discussed.
