Boron-doped diamond (BDD) exhibits p-type semiconducting behavior at low impurity concentrations, metallic conductivity at high concentrations, and can even become superconducting at low temperatures. On the other hand, nitrogen-vacancy (NV) centers in diamond are stable qubits across a wide range of temperatures, pressures, and chemical environments. In this presentation, we report the coherent quantum control of NV centers by applying high-frequency current through a circuit made of boron-doped diamond.
