Summary: The dominant commercial supplier of zero-field SERF optically pumped magnetometers (QZFM); its sensors underpin most of the world's wearable OPM-MEG systems.
Notes:
Osborne develops QuSpin's zero-field OPM sensors and their integration into research and OPM-MEG systems. The work complements NV-center diamond ensemble quantum sensing (DEER, NMR, T1 relaxometry) at pT/sqrt(Hz) sensitivity by pursuing the same field-sensing goals in a different physical platform.
Shah founded QuSpin, which commercialised the compact zero-field (SERF) OPM (QZFM) that underpins most wearable OPM-MEG systems worldwide; he continues to advance sensor sensitivity, dynamic range and multi-axis operation. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
