Summary: Co-supervises the Laboratoire Kastler Brossel (LKB) — one of the world's premier quantum optics laboratories, with 3 Nobel Prizes. Key groups at Jussieu relevant to quantum sensing: Treps/Parigi (multimode quantum optics, frequency-comb quantum metrology — directly applicable to astronomical spectrograph calibration and quantum-enhanced sensing); Gigan (wavefront shaping for deep-tissue imaging, quantum multimode optics in scattering media — breakthrough bio-sensing); Cohadon/Heidmann/Jacqmin (optomechanics, radiation-pressure sensing, back-action evasion, superconducting electromechanics). Exceptional for quantum-enhanced bio-imaging and optical quantum metrology for astronomy.
Notes: Formerly Pierre and Marie Curie University (UPMC). Co-supervises the Laboratoire Kastler Brossel (LKB) jointly with ENS, Collège de France, and CNRS — 3 Nobel Prizes, one of the world's premier quantum physics laboratories. Key LKB groups hosted at Jussieu campus: Quantum Optics / Multimode Quantum Optics (Treps, Parigi — squeezed light, frequency-comb quantum metrology), Quantum Fluids of Light (Glorieux, Bramati — polaritons, nanophotonics), Quantum Networks (Laurat — quantum memory, photon-atom interfaces), Optical Imaging in Complex Media (Gigan — wavefront shaping, deep-tissue imaging, quantum multimode optics), Optomechanics & Quantum Measurements (Cohadon, Heidmann, Jacqmin — radiation-pressure sensing, back-action evasion, superconducting electromechanics). Campus provides shared optics facilities and SPEC cleanroom access.
Parigi co-leads the Multimode Quantum Optics group at LKB alongside Treps. Research directions: (1) Multimode squeezed-state quantum networks — generating large-scale entangled cluster states using optical frequency combs; reconfigurable graph-state topologies for measurement-based quantum computing and distributed quantum sensing; (2) Multimode quantum sensing — using multimode squeezed states for simultaneous beyond-shot-noise estimation of multiple parameters (wavelengths, phases) in a spectrometer; (3) Non-Gaussian quantum states — heralded subtraction and addition of photons to Gaussian cluster states for universal CV quantum computation; (4) Quantum networks at telecom — generating multimode squeezed states compatible with fiber transmission. ERC Laureate. Employed by Sorbonne Université.
Treps leads the Multimode Quantum Optics group at LKB. Research directions: (1) Multimode quantum frequency combs — synchronously pumped OPO (SPOPO) generates entangled networks of squeezed modes with configurable graph structure; first demonstration of quantum frequency comb with multimode squeezing (PRL 2012); (2) Quantum-enhanced multiparameter estimation — quantum Fisher information and multimode squeezing for simultaneous beyond-shot-noise parameter estimation (e.g., frequency comb spectral centroid and energy, PRX 2020); (3) Non-Gaussian quantum states — heralded generation of non-Gaussian cluster states for CV quantum computing; (4) Quantum metrological inequalities — relating non-locality to parameter estimation. Spin-off: Cailabs (multimode fiber light-shaping for telecom and industrial lasers). Co-director of QICS. ERC-funded.
