Combes is a theorist of continuous quantum measurement, quantum trajectories, quantum-limited amplification and quantum filtering, with a strong record of working directly alongside superconducting-circuit and optical experiments rather than in isolation. Recent directions include the fundamental limits of amplifier-based sensing, error-corrected and adaptive metrology protocols, and characterisation/verification of noisy quantum devices. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his work supplies the estimation-theoretic scaffolding — quantum Fisher information, back-action limits, adaptive protocols — that determines whether an NV ensemble running DEER or nanoscale NMR at pT/sqrt(Hz) is actually operating at its fundamental bound or leaving sensitivity on the table. Theory PI, but explicitly experiment-facing.
Daniel Comparat (DR CNRS, LAC MFC coordinator) works on cold atoms, molecules and Rydberg physics. Research: (1) Rydberg atoms — spectroscopy, few-body interactions, frozen Rydberg gases with Cs/Yb; (2) cold molecules — BaF laser cooling and trapping for eEDM measurement; (3) antihydrogen laser manipulation for fundamental tests; (4) novel electron electric dipole moment measurement technique; (5) cold ion and electron sources (photo-ionization of laser-cooled atoms). ERC-linked funding.
Congreve engineers excitonic materials -- perovskite nanocrystals and molecular sensitizer/annihilator pairs -- for photon upconversion, light emission, and sensing applications, with interests extending toward quantum-technology-relevant nanoscale light-matter devices. [Borderline match: materials/energy focus with a sensing angle rather than a core quantum-sensing program; kept for review.]
Conolly builds Magnetic Particle Imaging (MPI) scanners, a tracer-based imaging modality that detects the nonlinear magnetization response of superparamagnetic nanoparticles with high sensitivity, safety, and zero background signal from tissue, alongside compressed-sensing MRI methods.
Cornell's group leads the JILA trapped-molecular-ion (HfF+/ThF+) search for the electron electric dipole moment - among the most sensitive tabletop probes of physics beyond the Standard Model - building on his Nobel-recognized work on Bose-Einstein condensation and precision measurement. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.
Cotter leads the Quantum Navigation research stream at Imperial's Centre for Cold Matter. He develops compact, fieldable cold-atom inertial sensors for GPS-denied navigation. Milestones: first demonstration of a cold-atom accelerometer on the London Underground (measuring acceleration/vibration in a real transit environment); successful field trials of quantum inertial sensors aboard the Royal Navy research ship XV Patrick Blackett (2023); Arctic field trials with Royal Navy (2025). His sensors use magnetically launched cold-atom Rb clouds and simultaneous multi-axis interferometry. He also contributes to AION-related atom interferometry work and the Quantum Technology Hub in Sensors and Timing. Department of Materials cross-appointment.
Courty provides theoretical support to LKB's optomechanics and quantum-measurement experiments, working on quantum-noise theory for radiation-pressure coupled cavities and standard-quantum-limit-evading measurement schemes.
Assembles optical-tweezer-trapped arrays of ultracold atoms and polar molecules (including NaRb) for quantum information science, quantum simulation, and cluster-state quantum computing, with associated Rydberg-based sensing capabilities.
Croot returned from Princeton to found Sydney's Superconducting Quantum Circuits Laboratory. The programme uses superconducting circuits both as quantum processors and as extremely sensitive probes: coupling microwave resonators and qubits to other degrees of freedom (mechanical modes, semiconductor structures, spins) to build hybrid systems, and developing the quantum-limited amplification chain that makes single-microwave-photon detection possible. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — superconducting circuits are the principal competitor technology for detecting the weak microwave signals that NV ensembles read magnetically; a quantum-limited or squeezed microwave amplifier is what lets an inductively-detected spin ensemble reach — and beat — the pT/sqrt(Hz) regime. Newly established, well-equipped lab; high autonomy for a postdoc and active recruitment as the lab builds out.
Croquette is a co-inventor of magnetic-tweezer single-molecule biophysics, applying it to helicase/topoisomerase mechanochemistry, DNA replication, and nucleic-acid mechanics; his group also develops complementary single-molecule readouts (stereo darkfield interferometry, mass photometry-adjacent tracking) for sub-nanometer 3D localization. He continues active, well-cited methodological development (e.g., recent reviews of magnetic-tweezer principles) alongside Jean-Francois Allemand.
