    Abstract

    The coherent oscillations among spin sublevels of a ground state single electron spin at room temperature were analyzed. The coherence was influenced by optical excitation and coupling to additional degrees of freedom, like single 14N nuclear spins of the nitrogen-vacancy (NV) center. It was shown that the measured dephasing times range from 1 to 2 μs. The results reveal the hyperfine interaction of the electron with the 14N nuclear spin of the defect center.
