Tim Freegarde's Quantum Control group develops atom interferometric sensors and matter-wave optics. Research: (1) optimal Raman pulse design for cold atom inertial sensors — geometric approach to π-pulse optimisation and robust control; (2) matter-wave interferometric velocimetry of cold atom clouds; (3) point-source interferometry for real-time scale-factor calibration of cold atom gyroscopes; (4) large-area atom interferometry. Part of the UK Quantum Technology Hub in Sensors and Metrology. Director of the CDT in Quantum Technology Engineering.

Rémi Geiger (CNRS DR, SYRTE/Observatoire de Paris; IUF 2020) leads atom interferometry for inertial sensing. Research: (1) interleaved cold-atom gyroscope — world record 3.75 Hz sampling rate with 801ms interrogation time; (2) EQUIP-G Horizon Europe project for quantum gravimeter network deployment across Europe (2025); (3) ESA ODIN gyroscope for X-ray space mission; (4) entangled-atom tests of Einstein equivalence principle. Key figure in precision cold-atom inertial sensors. Note: formally at SYRTE (PSL/Obs. Paris), entered under ENS (same PSL network).

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.
