Color-Center-Based Quantum Sensing

The spectroscopic properties of the nitrogen- and silicon-vacancy centers in diamond are exquisitely sensitive to the local magnetic, electric, and temperature environment. Using these unique properties of diamond color centers, we have developed quantum proximal sensors that can detect individual nuclear and electron spins on the diamond surface and perform spectroscopic investigations of chemical, biological, and condensed matter systems. These new quantum sensors open the door for NMR and MRI investigations of individual molecules and provide a new way to interrogate the physical, chemical, and biological systems with unprecedented sensitivity and spatial resolution.
