Because of hyperfine interaction between the host 14N nuclear spin and the nitrogen-vacancy centre electron spin, different orientations of the 14N nuclear spins lead to a triplet splitting of the transition between ground state (ms =0) and excited state (ms =1). The manipulation of the single electron spin of nitrogen-vacancy centre is achieved by using a combination of selective microwave excitation and optical pumping at 532 nm. Microwaves can excite three transitions equally to induce three independent nutations and the shape of Rabi oscillations is a combination of the three nutations.
