Tim Taminiau (QuTech team leader, Assoc Prof) develops NV-center quantum registers for sensing and quantum networks. Research: (1) NV-center nuclear spin registers — quantum control of up to 50 coupled 13C nuclear spins; (2) nanoscale NMR sensing — mapping external spin networks with sub-nm resolution; (3) silicon-carbide spin qubits — VSi centres for scalable quantum networks with fast entanglement rates; (4) quantum error correction in multi-spin diamond registers. NWO Vici Grant 2026. Quadrupolar nuclear spin spectroscopy of individual nuclei (Nano Letters 2024). Key for sensing proteins at nanoscale.
Toeno van der Sar's group uses NV-centre diamond magnetometry to study correlated spin dynamics and electric currents in magnetic and 2D materials. Research directions: (1) scanning NV magnetometry of topological magnets, 2D magnetic materials (CrI3, Fe3GeTe2), and superconductors; (2) spin-wave (magnon) spectroscopy in magnetic thin films using NV sensors; (3) widefield NV imaging of biological samples and materials. The group develops both NV scanning probes and widefield NV ensembles for nanoscale spatial mapping of magnetic phenomena.
Wrachtrup is a founder of NV-centre quantum sensing: single-spin and ensemble magnetometry, nanoscale/single-molecule NMR and ESR, nuclear-spin registers, scanning-probe quantum-materials imaging, and programmable diamond nanosensors for chemistry and biology. His group actively recruits postdocs across NV sensing and quantum technology. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is the reference point, extending DEER/nano-NMR toward single-molecule and cryogenic regimes.
Yacoby's lab develops scanning-probe quantum sensors, most notably scanning single-NV-center magnetometers and SQUID-on-tip probes, to image nanoscale magnetic textures and current flow in quantum materials at cryogenic and millikelvin temperatures. This scanning-probe approach extends the sensitivity and spatial resolution of NV ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry), which established pT/√Hz-class magnetometry, down to single-spin, nanometer-scale imaging of individual quantum materials.
