The nitrogen-vacancy (NV) center in diamond is the most prominent defect in diamond due to its outstanding properties as a quantum light source and its manipulable electron spin. NV applications range from quantum information processing to high sensitivity nano-magnetometry.
We discuss our recent progress of the population swapping via microwave Raman transitions in the multilevel electronic ground state of a single NV center. The here presented scheme relies on the polarization of the nuclear spin of the NV center at low magnetic fields. This hyperpolarization of the NV center's intrinsic nitrogen-15 can be achieved by recursive polarization via the NV center's electron spin [1,2].
