| Research Abstract |
In construction of scalable quantum network for quantum communication and computing, development of a few optically accessible quantum bits in solid is important. Recently, single NV center in diamond has been interested. In our research, by using <13>^C enriched and <12>^C enriched diamond samples, 4 qubit system of single NV center was observed and the longest T_2 of electron spin in solid at room temperature was realized.
