Description: DC/AC magnetic field sensing via ODMR of nitrogen-vacancy centers in diamond.
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/âHz-class magnetometry, down to single-spin, nanometer-scale imaging of individual quantum materials.
Yao works at the interface of theoretical and experimental many-body physics and quantum sensing, using dense NV-diamond spin ensembles and Hamiltonian engineering to push magnetometry and nanoscale NMR beyond standard-quantum-limit sensitivities. His work is a direct extension of the original NV ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry) that achieved pT/âHz sensitivity, adding many-body-enhanced protocols and error-correction-assisted sensing on top of that foundation.
Zheltikov integrates NV-diamond magnetometry into photonic-crystal fibers for high-resolution, fiber-delivered magnetic-field imaging and endoscopy, alongside ultrafast biophotonics (multiphoton deep-tissue imaging, SWIR probes) and quantum-light molecular spectroscopy. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work extends NV ensemble sensing into fiberized, in-vivo-compatible geometries.
