QuantumSong is a Copenhagen-based research accelerator developing ruggedized laser-pumped optically-pumped magnetometer (OPM) cells and gradiometers for geophysical applications. Established as the joint R&D arm of Canadian magnetometer manufacturers GEM Systems (land/airborne) and Marine Magnetics (marine), QuantumSong applies quantum-optical sensing technology with research lineage from the Niels Bohr Institute Quantop group to industrial-grade magnetometers for air, land, marine, and VLF surveying.
