The V2 color center in Silicon Carbide is a promissing candidate for scalable quantum networks due to its long coherence time, electrical compatibility, hosting two different and individually addressable nuclear spin bathes[1].
In this work, we resolve the nuclear spin environment of a single color center using Electron DOuble Nuclear Spin Resonnance (ENDOR) spectroscopy showing over ten addressable nuclear spins and demonstrate their individual initialisation and control. We furthermore show first results on the entanglement of two weakly coupled nuclear spins.
