| Research Abstract |
By using the NV centre in diamond, we demonstrated strong coupling between a solid-state quantum processing unit (a flux-qubit) and a dedicated quantum memory (NV centers). Furthermore, we reported the realization of electrically driven single photon source at room temperature by using the NV centre by making p-i-n diode structure. In addition, we demonstrated the electrical manipulation of the negative charge state of single nitrogen-vacancy defect centers (NV-) in diamond for the first time. We consider that our achievement is a crucial step towards elaborated diamond-based quantum information devices which is operated by single spin, single photon, and single charge.
