Department(s)/lab(s): CEA-Leti / Mag4Health | He-OPM MEG (Mag4Health) @ CEALeti
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.

Department(s)/lab(s): Department of Clinical Neuroscience / NatMEG | NatMEG @ Karolinska
Summary:

Lundqvist directs Sweden's national MEG facility (NatMEG), running SQUID- and OPM-MEG for cognitive and clinical neuroscience and OPM method development. 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.

Department(s)/lab(s): Department of Imaging Neuroscience (FIL) | UCL OPM-MEG (Dept. of Imaging Neuroscience) @ UCL
Summary:

Mellor works on magnetic-field mapping and movement-artefact correction for moving OP-MEG and on ictal/clinical OP-MEG recordings. 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.

Department(s)/lab(s): Department of Clinical Neuroscience / NatMEG | NatMEG / on-scalp MEG @ Karolinska
Summary:

Pfeiffer develops on-scalp MEG with OPM and high-Tc SQUID sensors and benchmarks them against conventional MEG. 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.

Tilmann Sander

Department(s)/lab(s): Biosignals Department | Optical Magnetometry (Working Group 8.21) @ PTB
Summary:

Sander(-Thoemmes) leads PTB's optical-magnetometry group, building multi-channel OPM-MEG systems in world-class shielded rooms and studying auditory/sensory brain responses, magnetic nanoparticles and clinical applications. 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.

Department(s)/lab(s): Institute of Neuroscience and Physiology / MedTech West | On-scalp MEG (MedTech West) @ Gothenburg
Summary:

Schneiderman develops on-scalp MEG using high-critical-temperature SQUIDs and OPMs, aiming for higher-resolution, lower-cost biomagnetometry. 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.

Department(s)/lab(s): Department of Imaging Neuroscience (FIL) | UCL OPM-MEG (Dept. of Imaging Neuroscience) @ UCL
Summary:

Tierney develops OPM-MEG signal-processing and array design: spherical-harmonic/vector interference rejection, spatial sampling of multi-axis OPMs, and SPM-based source reconstruction, and led early clinical OP-MEG validation. 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.
