Strong coupling of nitrogen-vacancy colour centers in nanodiamonds

Nitrogen vacancy centers in nanodiamonds, due to their temporal stability, spacial dimensions and long coherence time, have shown to be suitable for a solid state approach to quantum technology such as quantum computing, metrology and sensing. Controlled strong coupling remains, however, a major challenge. Possible mechanisms include coupling mediated by the spin bath of surrounding carbon atoms or plasmons travelling along a silver wire between two nanodiamonds with point defect. The observation of spin waves and two qubit operations is the final goal.
