Quantum Sensing

Quantum sensing exploits the unique properties of quantum systems—such as superposition and entanglement—to achieve measurement precision far beyond classical limits. Color-center–based quantum sensing uses atomic-scale defects in crystals (like nitrogen-vacancy centers in diamond) as ultra-sensitive quantum probes. These defects behave like artificial atoms embedded in a solid, with electronic spin states that can be controlled and read out using light and microwaves.Key advantages: (i) Room-temperature operation (especially with NV centers in diamond), (ii) High sensitivity to magnetic fields, electric fields, temperature, and pressure, and (iii) Nanoscale resolution, since color centers can be placed very close to the sample.
