Summary:

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 Sm⁻¹ 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.

Department(s)/lab(s): Physics (Cavendish Laboratory – AMOP Group) | Many-Body Quantum Dynamics Group @ Cambridge
Summary:

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.

Department(s)/lab(s): Applied Physics | Semeghini Lab @ Harvard
Summary:

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.

Department(s)/lab(s): Physics | Sinclair Lab (IMAQ Lab) @ UWMadison
Summary:

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.

Department(s)/lab(s): Physics (Clarendon Laboratory) | Dipolar Quantum Gases Group @ Oxford
Summary:

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.

Department(s)/lab(s): Physics | Stamper-Kurn Ultracold Atoms Lab @ UCB
Summary:

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.

Department(s)/lab(s): Physics – QOLS / Centre for Cold Matter | Centre for Cold Matter – eEDM / Precision Molecular Sensing @ Imperial
Summary:

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, 2Γ—10^5 molecules/shot, eEDM sensitivity of 1.8Γ—10^βˆ’28 eΒ·cm/day (near shot-noise limit); (2) YbF 3D optical lattice β€” aiming for 10^βˆ’30 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.

Department(s)/lab(s): Physics – QOLS / Centre for Cold Matter | Centre for Cold Matter – Ultracold Molecular Spectroscopy (Truppe) @ Imperial
Summary:

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).

Department(s)/lab(s): Physics | Experimental Atomic Physics Group (Vuletic Lab) @ MIT
Summary:

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.
