Spins associated to atomic scale defects in solids are attractive as sensitive probes and are promising candidates for quantum information processing (QIP) [1]. Our research is based on spin defects in silicon carbide (SiC), a technologically-relevant
wide-bandgap semiconductor which offers spin-active defects with long coherence times at room temperature [2]. In this work, we extend our previous single spin study [2] by investigating optical and spin properties of the silicon vacancy in 4H-SiC via resonant optical and spin driving and discuss their potential use for quantum computing and quantum communication [3].
