NV-Center Quantum Magnetometer Simulator

Interactive nitrogen-vacancy (NV) center quantum sensing simulator: sweep a microwave frequency across the spin resonance of a diamond defect, watch the ODMR fluorescence dip split under an applied magnetic field, and measure the field from the Zeeman splitting.

This simulator models optically detected magnetic resonance (ODMR) on a single nitrogen-vacancy center in diamond. A green laser continuously pumps the defect while a microwave field is swept across its spin resonance; the resulting fluorescence dip splits into two under an applied magnetic field via the Zeeman effect. Drag the two cursors on the live spectrum onto the dips to read the splitting and recover the field strength, mirroring how a real NV magnetometer senses nanoscale magnetic fields at room temperature.
