Summary:

Labyt led development of metastable helium-4 OPMs at CEA-Leti and co-founded Mag4Health to commercialise room-temperature 4He OPM-MEG with large dynamic range and native 3D vector output. 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.

Summary:

Le Prado develops the helium-4 OPM sensor technology and instrumentation behind Mag4Health's 4He 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.

Summary:

Palacios-Laloy develops metastable helium-4 and alkali OPMs at CEA-Leti, including SERF-regime and vector magnetometers and their noise characterisation for MEG and sensing. 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.
