Sylvain Gigan's PICO (Photonics, Information, and Complexity) group focuses on imaging through and with complex and scattering media. Research: (1) wavefront shaping through scattering media — adaptive optics and transmission matrix approaches for deep-tissue fluorescence imaging; (2) multimode quantum optics through complex media — pushing quantum light through scattering and multi-mode fibres; (3) analogue computing with random optical scattering media. Key for biosensing: deep tissue imaging at high spatial resolution and quantum-enhanced light manipulation.

Gleyzes is a CNRS researcher in the Rydberg Atoms team at LKB (successor to Serge Haroche's cavity-QED group), where he achieved the first quantum non-demolition detection of a single microwave photon. The team now prepares non-classical states of circular Rydberg atoms as probes for electric- and magnetic-field sensing below the standard quantum limit, uses quantum optimal control to navigate large Rydberg Hilbert spaces, and has demonstrated millisecond-lived circular states at room temperature, a route toward practical Rydberg-atom quantum sensors and simulators.

Glorieux leads the Quantum Fluids of Light and Nanophotonics group at LKB. Research directions: (1) Quantum fluids of light in atomic vapors — hot Rb/Cs vapor as paraxial photon fluids exhibiting superfluidity, soliton dynamics, and vortex formation; first analogue cosmological particle creation (Hawking effect) in a photon fluid (Nature Communications 2022); (2) Polariton superfluids — exciton-polariton microcavities for analogue gravity, Bogoliubov dispersion mapping, and first-order dissipative phase transitions; (3) Nanophotonics — coupling single quantum emitters (nanofiber-coupled atoms, perovskite nanocrystals) for quantum photonics and sensing; displacement sensor based on optical nanofiber; (4) Optical computing interfaces with quantum systems. Marie Curie IOF Fellow (2011), City of Paris Young Scientist Award (2015).

Quentin Glorieux's group explores quantum fluids of light and polariton physics. Research: (1) exciton-polariton condensates in semiconductor microcavities — superfluidity, vortex dynamics, analogue gravity; (2) quantum fluids of light in atomic media — photon-photon interactions via electromagnetically induced transparency; (3) analogue gravity with polariton and photon fluids — studying acoustic black hole analogs with quantum light. IUF member; ERC grants.

Goldfarb studies coherent effects in atomic vapours - EIT and slow light, spin-noise spectroscopy of spin-environment interaction, and EIT-based Rydberg-atom radio-frequency field sensing (electrometry) in warm cells. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work adds atomic-vapour electrometry and coherence spectroscopy.

Studies experimental quantum optics and atomic physics, including quantum light-matter interfaces, quantum memories, and single-photon sources based on atom-like emitters in solids, for applications in long-distance quantum communication and quantum networking.

Golwala's group develops ultrasensitive cryogenic detectors - phonon-mediated devices and kinetic-inductance/TES arrays - for direct dark-matter detection (SuperCDMS) and millimeter/submillimeter astrophysics and CMB measurements, working closely with JPL on detector technology. For context, this complements the established paradigm of NV-diamond ensemble magnetometry (Hahn-echo/DEER, nanoscale NMR, T1 relaxometry) operating near pT/√Hz sensitivity.

Graham is a theoretical physicist whose phenomenological proposals directly motivate several leading quantum-sensing experiments -- co-designing the MAGIS atom-interferometer program for gravitational waves and ultralight dark matter, and the DMRadio lumped-element axion search -- bridging fundamental theory with concrete experimental sensor concepts rather than running his own lab. [Included as a borderline/theory-side match per filter guidance; kept for review.]

Experimental astroparticle physicist searching for dark matter with noble liquid detectors. Directions: (1) DarkSide-20k — liquid argon TPC at INFN Gran Sasso targeting WIMP dark matter with 20-tonne active volume; (2) development of cryogenic SiPM photon detection for LAr detectors; (3) low-background detector techniques and radon mitigation; (4) argon purification and light yield optimization.

Grange leads the Optical Nanomaterial Group at ETH, developing nonlinear materials for quantum photonic integrated circuits. Research directions: (1) Barium titanate (BTO) nanophotonics — scalable CMOS-compatible BTO thin-film integrated circuits exploiting large χ(2) nonlinearity for quantum entangled photon-pair generation via SPDC; (2) Lithium niobate on insulator (LNOI) — quantum photonic integrated circuits for heralded single-photon sources and electro-optic transduction; (3) Second-harmonic generation sensing — SHG-active nanocrystals as contrast agents and phase-sensitive probes in biological imaging; (4) On-chip entangled photon sources for quantum communication and sensing. Strong quantum sensing application in nonlinear optical readout of quantum states.
