Ramsey-based diamond quantum magnetometer for biomagnetic sensing

Caption

The sensor combines a light-trapping diamond waveguide with Ramsey interferometry to detect magnetic fields. Using a 210 mW laser, it limits the temperature rise to 13 K while achieving a 3 pT/√Hz sensitivity at a 2.0 mm sensor-to-sample distance.
