Mueller's group performs light-pulse atom interferometry at extreme precision to test the equivalence principle, measure the fine-structure constant, and search for new physics, developing techniques (large momentum transfer, squeezed-atom methods) that also underlie compact atom-interferometric gravimeters and gyroscopes. The lab is actively recruiting postdocs.
Franck Pereira dos Santos (CNRS DR, SYRTE) develops dual-species (Rb/Cs) atom interferometers and gravimeters with the highest accuracy. Research: (1) cold-atom gravimeters for absolute gravity measurement; (2) dual Rb/Cs fountain for equivalence principle tests; (3) interleaved interferometry to eliminate dead-time and aliasing noise; (4) quantum optimal control for Raman/Bragg pulse sequences. Key SYRTE inertial sensor PI.
John Rarity's group works on quantum-enhanced measurements and free-space quantum key distribution. Research: (1) quantum imaging with undetected photons — mid-infrared gas sensing (CO2, CH4) exploiting entangled photon pairs, with only near-IR photons detected (startup QLM); (2) sub-shot-noise imaging using quantum-identical photon beams; (3) spin-photon interfaces (1D cavity with near-unit scattering efficiency); (4) compact satellite QKD transmitters (EPSRC Quantum Comms Hub). Highly relevant to quantum-enhanced sensing.
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.
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.
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.
