Renzoni's group is internationally recognized as a pioneer in electromagnetic induction imaging (EMI) with optical atomic magnetometers. Research directions: (1) All-optical 87Rb atomic magnetometer MIT β demonstrated first magnetic induction tomography (MIT) with atomic magnetometers (2013), first EMI of biological tissues below the 1 Smβ»ΒΉ threshold (Applied Physics Letters 2020), enabling non-invasive cardiac conductivity imaging; (2) Unshielded RF atomic magnetometer operation with general regression neural network auto-optimization; (3) Non-destructive evaluation β industrial corrosion/defect imaging via quantum-sensitive MIT; (4) Sub-Fourier signal processing with nonlinear systems for frequency resolution beyond classical limits. Collaborates with NPL on quantum sensing standards. Applications span medicine (atrial fibrillation), security, and materials inspection.
Stefan SchΓ€ffer leads the Quantum Metrology group at NBI together with JΓΆrg MΓΌller. Research focuses on superradiant strontium lasers: (1) quasi-continuous superradiant lasing with sub-natural linewidth; (2) Ramsey spectroscopy enhanced by cavity sub-to-superradiant phase transitions for improved atomic clock sensing; (3) continuous atom beam for Dicke-effect-free superradiant interrogation. Key work published in PRL (2023) and Nature Communications (2024). Part of EU iqClock and ESA collaborations.
Schneider leads the Many-Body Quantum Dynamics group. His primary work is on optical lattice quantum simulation with ultracold atoms (quasicrystalline and kagome potentials, non-equilibrium dynamics), but he also co-leads a significant quantum sensing arm: he is a core Cambridge PI in the AION collaboration building a 10 m strontium single-photon atom interferometer at Oxford and contributing to MAGIS-100 at Fermilab, targeting mid-band gravitational wave detection and ultralight dark matter. In 2026 he co-leads the UKRI-funded SEQUIN project, a hybrid quantum-classical interferometer array combining atom interferometry with seismometers to probe gravitational waves and Earth's interior.
Semeghini is an experimentalist studying quantum simulation of complex materials using Rydberg-atom tweezer arrays; she joined the SEAS Applied Physics faculty after a postdoctoral appointment in Mikhail Lukin's group. Included as a borderline, not-preferred case: the Rydberg-tweezer platform overlaps with quantum-sensing hardware, though her stated focus is quantum simulation rather than sensing per se.
Builds neutral-atom-array platforms coupled to optical cavities to explore nonlocal entanglement for modular fault-tolerant quantum computing and distributed quantum sensor networks; also works on quantum error correction and quantum foundations.
Smith's Dipolar Quantum Gases group builds ultracold erbium (and Er-K mixture) experiments to study the effect of long-range, anisotropic dipole-dipole interactions on many-body quantum phenomena including supersolidity, turbulence and impurity/polaron physics.
Stamper-Kurn's group uses site-resolved quantum-gas microscopy and cavity optomechanics with ultracold atoms to study strongly correlated many-body quantum matter and quantum measurement backaction, techniques that double as some of the most sensitive atom-based force and field sensors available.
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 β 2D transverse laser cooling producing 200 ΞΌK, 2Γ10^5 molecules/shot, eEDM sensitivity of 1.8Γ10^β28 eΒ·cm/day (near shot-noise limit); (2) YbF 3D optical lattice β aiming for 10^β30 eΒ·cm/year, requires laser cooling to ΞΌK 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 AΒΉΞ βXΒΉΞ£βΊ transition, making it a candidate for high-density laser trapping; MgF is characterised for its AΒ²Ξ βXΒ²Ξ£βΊ 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.
