Nitrogen-Vacancy Center Hybridization with External Emitters Leading to Improved Sensing Capabilities

Nitrogen-Vacancy (NV) centers in diamond are one of the most robust and promising quantum sensing platforms. The possibility of initializing the spin state via green laser pumping combined with its differentiated photoluminiscence for the ± 1 spin states compared to the 0 spin state allows to use the center for sensing AC and DC magnetic fields, temperature, material strain and electrical fields [1].
