Colour centres in diamond have demonstrated a remarkable versatility for various applications in quantum information processing, magnetometry and in biological systems. Among them, the silicon-vacancy centre (SiV) is attracting an increasing attention due to its strong fluorescence into its zero-phonon line as well as its recently evidenced ground state spin, making it a potential candidate as a spin-photon interface. We here present our recent realisation of coherent population trapping on a single SiV, in which we optically create a coherent superposition of spin in the ground state. This allows us to determine for the first time a coherence time for the spin state in this system.
