défaut azote-lacune ou center NV; Nitrogen-Vacancy center

An NV center is a defect in the diamond crystal structure consisting of a nitrogen atom adjacent to a gap. It behaves like an artificial atom, with discrete energy levels located in the diamond band gap. In its negatively charged state, it has an electron spin $S$ = 1, whose magnetic resonance is measured using the NV center as a quantum sensor.

ODMR (Optically Detected Magnetic Resonance)

Optical measurement of magnetic resonance in systems such as the NV center, whose photoluminescence signal depends on the spin state. By inducing the magnetic transition between a bright and a dark state using microwave excitation, magnetic resonance can be precisely localized....
