The ability to investigate weakly coupled nuclear spins via electron spin ancillae offers great potential for novel quantum sensing applications. Nitrogen-Vacancy centers in diamond with long spin coherence times (several ms) are promising solid state systems for quantum information processing and detection at room temperature.
In high magnetic fields single shot readout schemes promise sensing below the Heisenberg limit. Here, we present recent results of nuclear spins coupled weakly to Nitrogen-Vacancy centers in low magnetic fields using dynamical decoupling techniques and isotopically enriched diamonds. Details on detection schemes and robust manipulation of 13C spins are discussed.
