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.

Department(s)/lab(s): Department of Physics | Experimental Quantum Optics and Photonics (EQOP) @ Strathclyde
Summary:

Riis co-leads EQOP, developing unshielded and MEMS-based optically pumped magnetometers (double-resonance, free-induction-decay) for geomagnetic sensing, magnetocardiography and magnetomyography, alongside atomic clocks and cold-atom devices. 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:

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.

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.

Summary:

Schwindt develops microfabricated and SERF optically pumped magnetometers and atomic sensors, including compact OPM arrays for MEG. 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:

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.

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.
