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.
Develops multidimensional coherent spectroscopy methods, including label-free multidimensional optical imaging/contrast techniques applied to cancerous tissue and nanoscale heterostructures.
Wurm's group builds and exploits large liquid-scintillator neutrino detectors, principally JUNO (reactor neutrinos, mass ordering) plus low-energy solar and geo-neutrino physics; work spans scintillator chemistry and optical purity, photosensor characterization, and reconstruction. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), included as a detector-instrumentation pivot -- the transferable content is ultra-low-noise photon counting and calibration at scale, not spin physics.
Wyatt studies the structure, composition and dynamical evolution of circumstellar debris discs (using ALMA, Herschel and JWST imaging) as tracers of hidden planetary systems, linking dust production, planetesimal collisions and planet-disc interactions to the broader picture of planet formation.
Wysocki develops quantum-cascade-laser-based spectroscopic sensing systems, including external-cavity QCLs, dispersion spectroscopy, and mid-IR dual-comb spectrometers, that routinely reach fundamental quantum-noise detection limits for trace-gas sensing; applications span atmospheric/environmental monitoring, drone-based methane leak detection, industrial process control, and human breath-based metabolic/medical diagnostics.
Xu leads the Experimental Quantum Engineering group with a joint ETH–PSI appointment. Research directions: (1) Superconducting circuit quantum sensing — using qubits-as-sensors for detecting weak microwave signals beyond standard quantum limits, quantum non-demolition readout of photon fields; (2) Quantum error correction enabled sensing — integrating bosonic codes (cat qubits, binomial codes) into sensing protocols; (3) Quantum acoustics — coupling superconducting qubits to surface acoustic wave (SAW) resonators for hybrid quantum sensing; (4) Novel quantum hardware at PSI — leveraging PSI's infrastructure for cryogenic device fabrication and testing. Connected to the ETH–PSI Quantum Computing Hub.
Xu works on frequency-dependent squeezed-light injection for quantum-enhanced gravitational-wave detection at LIGO and on trapped-cavity atom interferometry for precision tests of fundamental physics, bridging quantum optics and atom-based inertial sensing.
Xu develops STORM and related single-molecule-localization super-resolution imaging methods, along with new fluorogenic and multiplexed labeling strategies, to visualize cellular ultrastructure at ~10-20 nm resolution. The group is actively recruiting postdocs.
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.
Yakovlev develops label-free biomedical imaging: Brillouin micro-spectroscopy of cell/tissue viscoelasticity, impulsive stimulated Brillouin scattering, SERS and coherent-Raman diagnostics, and quantum-enhanced (photon-number-resolving, sub-shot-noise) optical imaging in collaboration with Agarwal/Scully. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work provides the biomedical, quantum-enhanced-imaging bridge for spin-sensor bio-applications.
