Summary: One of Europe's largest and most productive AMO/quantum sensing groups. The QOLS group at the Blackett Laboratory (~15 academics, 30 postdocs, 50+ PhD students) spans cold matter (CCM: eEDM/YbF, atom interferometry for inertial/gravitational sensing), attoscience, quantum navigation, and biophotonics (FLIM, super-resolution). Imperial leads the AION consortium for atom interferometry (dark matter, gravitational waves). The Quantum Science and Device Facility (QSDF) and Blackett cleanroom support device work. Exceptionally strong for astro-oriented quantum sensing (AION, gravity gradiometry) and emerging biophotonics.
Notes: Top-10 global research university, ranked #2 in UK. The Department of Physics at the Blackett Laboratory hosts the Quantum Optics and Laser Science (QOLS) group โ ~15 academic staff, 30 postdocs, 50+ PhD students โ one of the largest AMO/quantum photonics groups in Europe. Key divisions: Centre for Cold Matter (CCM; eEDM/YbF, cold molecules, atom interferometry, quantum navigation), Laser Consortium (attoscience), Controlled Quantum Dynamics (theory), and Photonics Group (FLIM/super-resolution biophotonics). Imperial is lead institution of the AION consortium for atom interferometry. Has cleanroom facilities in the Blackett Building and a shared Quantum Science and Device Facility (QSDF). Cost of living in London is high (~ยฃ3,600/month). Very strong quantum technology ecosystem via QuEST and EPSRC Quantum Technology Hub.

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 โ 2D transverse laser cooling producing 200 ฮผK, 2ร10^5 molecules/shot, eEDM sensitivity of 1.8ร10^โ28 eยทcm/day (near shot-noise limit); (2) YbF 3D optical lattice โ aiming for 10^โ30 eยทcm/year, requires laser cooling to ฮผK 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.
Thompson leads the Ion Trapping Group at Imperial using RF (Paul) traps with laser-cooled Ca-40 ions and Penning traps. Research foci: (1) High-fidelity quantum logic gates โ optimal control techniques for single-ion state manipulation and two-qubit gates; demonstrated >1 s coherence times via Ramsey interferometry in a Penning trap; (2) Precision spectroscopy โ ytterbium ion optical clock uncertainty characterisation at 2.2ร10^โ18 fractional uncertainty (NPL collaboration); proposed precision laser spectrometer for highly charged ions (HCI) in cylindrical Penning traps for QED tests; (3) Axion sensing โ collaborating with Devlin on the Penning-trap single-electron photon counter for axion searches; (4) Coulomb crystals โ ultrahigh resolution spectroscopy of ion crystals. Past work includes SPECTRAP project at GSI Darmstadt for HCI 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 Aยนฮ โXยนฮฃโบ transition, making it a candidate for high-density laser trapping; MgF is characterised for its Aยฒฮ โXยฒฮฃโบ 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).
Unruh studies stellar magnetic activity, starspots and irradiance variability and their effect on exoplanet transit and radial-velocity observations, helping to characterise host stars for precise exoplanet measurements.
Vanner leads the Quantum Measurement Lab, combining experiment and theory. Key research areas: (1) Cavity quantum optomechanics โ developed a theoretical framework capturing nonlinear radiation-pressure beyond the linearised approximation, showing deterministic mechanical Wigner-negativity generation; demonstrated mechanical position-squared measurements in Nature Comms (2016); thermal noise squeezing by 36 dB (Nat. Comms 2013); (2) Brillouin-Mandelstam scattering โ demonstrated strong coupling to high-frequency phonons (Optica 2019); single-phonon addition/subtraction via Brillouin (PRL 2021); quantum state tomography with non-Gaussianity; (3) Hybrid quantum systems โ 'displacemon' architecture (nanobeam magnetically coupled to superconducting qubit, PRX 2018) for testing objective collapse and dark matter; (4) Quantum gravity tests โ proposals for testing the generalised uncertainty principle (GUP) using optomechanical protocols.
