Nitrogen vacancy centre-based diamond microscope for investigating quantum materials

In the past few years, there has been a growing interest in materials that show topological phases and macro-scale quantum correlations. Innovative measurement techniques with high spatial and temporal resolution are necessary to study these materials and develop technological applications using them. Nitrogen vacancy centres in diamond offer the unique possibility of non-perturbative nanoscale sensing with high sensitivity. Additionally, nitrogen vacancy centres are also capable of simulating the Hamiltonian dynamics of quantum materials. In this review, we discuss the frontiers of applying nitrogen vacancy-based quantum sensors for imaging and simulating novel quantum materials.
