    "abstract": "Rabi nutations of a single nuclear spin in a solid have been observed. The\nexperiments were carried out on a single electron and a single 13C nuclear spin\nof a single nitrogen vacancy defect center in diamond. The system was used for\nimplementation of quantum logical NOT and a conditional two-qubit gate (CROT).\nDensity matrix tomography of the CROT gate shows that the gate fidelity\nachieved in our experiments is up to 0.9, good enough to be used in quantum\nalgorithms.",
