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.

Tarbutt co-leads the Imperial eEDM experiment using YbF molecules and runs an independent molecular array quantum computing/sensing programme. Two parallel eEDM experiments: (1) Ultracold YbF beam — 2D transverse laser cooling producing 200 μK, 2×10^5 molecules/shot, eEDM sensitivity of 1.8×10^−28 e·cm/day (near shot-noise limit); (2) YbF 3D optical lattice — aiming for 10^−30 e·cm/year, requires laser cooling to μK and loading into 3D optical lattice, using novel all-optical spin polarisation and analysis. Also leads UKRI project on testing fundamental physics using arrays of ultracold molecules (CaF in optical tweezers for two-qubit molecular gates). These experiments probe CP-violation and BSM physics at PeV energy scales through precision molecular spectroscopy.

Truppe is an Associate Professor at the Centre for Cold Matter, specialising in laser cooling of atoms and diatomic molecules using deep-UV lasers. His current focus is aluminium monofluoride (AlF) and magnesium fluoride (MgF): AlF can be produced in a bright cryogenic buffer-gas beam and rapidly optically cycled on the A¹Π↔X¹Σ⁺ transition, making it a candidate for high-density laser trapping; MgF is characterised for its A²Π↔X²Σ⁺ hyperfine structure, relevant to laser cooling. These molecules open routes to ultracold chemistry studies, precision spectroscopy, and quantum simulation. Truppe returned to Imperial as faculty after a period at the Fritz Haber Institute (ERC Starting Grant, 'CoMoFun', cold molecules for fundamental physics).

PREFERRED. Vuletic's group generates large-scale spin squeezing and entanglement in cold and ultracold atomic ensembles to push optical atomic clocks and rotation/field sensors below the standard quantum limit, alongside work on cavity QED, Rydberg tweezer arrays, and nonlinear quantum optics at the single-photon level. Recent work includes cavity-feedback spin squeezing for ytterbium clocks and fault-tolerant neutral-atom quantum sensor/processor arrays with collaborators at Harvard.

Walz works on precision spectroscopy of exotic atoms and antimatter. The group is known for continuous-wave Lyman-alpha (121.6 nm) laser sources -- the enabling technology for laser cooling of antihydrogen -- and for antihydrogen and positronium spectroscopy aimed at CPT tests and at antimatter gravity measurements, in collaboration with CERN antiproton-decelerator experiments. Complementary work at Mainz covers laser development, exotic-atom trapping and detection. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is a fundamental-symmetry pivot: the sensing content is in ultra-stable lasers, extreme-vacuum trapping and single-particle detection rather than solid-state spins, and it suits a postdoc looking to move from quantum sensors toward fundamental-physics tests.

Carrie Weidner's GECKO group develops experimental quantum sensing and simulation with cold atoms and hot atomic vapours. Key directions: (1) robust atom interferometry for 6-axis inertial sensing using optical lattice potentials (EPSRC-funded, Infleqtion partnership); (2) magnetic field imaging with squeezed light in hot atom vapour cells (wide-field OPM-type sensing using Faraday rotation); (3) quantum optimal control theory for atom interferometric sensors. The group is establishing a full ultracold atom apparatus for quantum simulation and sensing. Active postdoc positions.

The LARISSA group develops multi-step resonance ionization laser spectroscopy and RIMS: element- and isotope-selective laser ionization used both as an ultratrace analytical technique (actinide detection at extreme selectivity, environmental and nuclear-forensic samples) and as a spectroscopy tool for exotic and short-lived isotopes, feeding ion-source development for facilities such as ISOLDE/CERN. A major current thrust is the atomic and ionic spectroscopy of thorium, including the 229mTh isomer that underpins the nuclear-clock effort, done jointly with Schmidt-Kaler's trap group and Duellmann's nuclear chemistry. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the transferable capability here is selective, quantum-state-resolved detection of single atoms/ions -- the readout problem, approached spectroscopically rather than magnetically.

Christoph Westbrook co-heads the Quantum Gases group at LCF/IOGS. Research: (1) metastable helium (He*) BEC and ultracold atomic gases — atom optics, Bose-Hubbard physics, Anderson localization; (2) correlated atom pair production via four-wave mixing for quantum atom optics sensing; (3) atom laser and matter-wave interferometry. The group pioneered the He* BEC and uses correlated atom pairs for quantum sensing analogous to two-photon quantum optics.

Windpassinger's group works on cold neutral atoms as both a platform for fundamental light-matter physics and a deployable sensing technology. The fundamental line uses dysprosium -- the most magnetic element -- to study light propagation in dense dipolar media, where interatomic spacings fall below the optical wavelength and light-induced plus magnetic dipole-dipole interactions produce cooperative effects (superradiance, subradiance); controlled transport in optical dipole traps and microfocusing let them tune from single-atom to collective behaviour. The applied line builds ultracold-atom quantum sensors that survive outside the lab: atom interferometers and BEC sources flown in the Bremen drop tower, on sounding rockets, and on the ISS, aimed at inertial sensing, gravimetry and tests of fundamental constants under microgravity. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is the complementary 'cold and fragile but absolutely calibrated' end of the sensing spectrum; the group's real distinguishing asset for a postdoc is the space/microgravity engineering pipeline, which is rare. The group states it is continuously looking for motivated researchers and lists open positions via the PI.

Witte's group builds table-top extreme-ultraviolet sources via high-harmonic generation and combines them with coherent diffractive imaging (ptychography) to visualize 3D nanostructures, such as multilayer IC features, at resolutions well below the diffraction limit of visible light. The lab also works on lensless microscopy, photoacoustic imaging/metrology, and ultrafast electron/HHG dynamics, sitting at the interface of fundamental attosecond-adjacent light-matter physics and applied nanometrology; the group is actively hiring as it ramps up at TU Delft.
