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.
