Antoine Browaeys' group at LCF/IOGS is a world leader in neutral atom quantum simulation using optical tweezer arrays. Research: (1) Rydberg atom tweezer arrays for quantum simulation of strongly correlated many-body systems and quantum sensing; (2) dipole-dipole interactions in Rydberg ensembles; (3) co-founder and key researcher of Pasqal (neutral atom quantum computing company). The group works on scalable neutral atom platforms relevant to quantum sensors and quantum simulation. Open postdoc positions (2026).

Michel Brune leads the Rydberg atoms / cavity QED group at LKB. Research: (1) circular Rydberg atoms trapped in high-finesse microwave cavities — quantum non-demolition measurement of photons, quantum state engineering; (2) fundamental quantum optics: decoherence, entanglement, quantum jumps, Schrödinger cat states; (3) quantum sensing of cavity fields with single atoms as probes. This group pioneered cavity QED experiments leading to the 2012 Nobel Prize (Haroche). Brune heads the laboratory.

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.

Igor Ferrier-Barbut (CNRS DR, LCF/IOGS) works on dipolar and Rydberg quantum systems for quantum simulation. Research: (1) dipolar dysprosium (Dy) quantum gases — magnetic dipole-dipole interactions, supersolids, quantum droplets; (2) sub-wavelength structured atomic arrays as quantum simulation platforms; (3) collective light-matter interactions in dense cold-atom ensembles. Jacques Herbrand Grand Prize 2022. ERC Starting Grant (CORSAIR). Works in the Browaeys/Lahaye quantum optics group.

Philippe Grangier is a pioneer of quantum optics and quantum information at the Laboratoire Charles Fabry (IOGS/École Polytechnique). Research: (1) foundations of quantum mechanics: single photon experiments, Bell tests, quantum non-demolition measurement; (2) quantum optics and quantum information — continuous variables, entanglement generation, quantum cryptography; (3) Rydberg atom experiments (in collaboration with Browaeys). Coordinator of SIRTEQ network (700+ quantum researchers in Île-de-France). Closely connected to Pasqal spinoff. Key for quantum sensing foundations.

Thierry Lahaye (CNRS DR, LCF/IOGS) co-leads the quantum optics atoms group with Browaeys and Ferrier-Barbut. Research: (1) Rydberg atom tweezer arrays for quantum simulation of many-body spin Hamiltonians; (2) dipole-dipole interaction physics with Rydberg atoms; (3) cryogenic tweezer arrays (2000-site rearrangement at 4K, PRApplied 2024). Key architect of Pasqal's quantum computing platform.

Levine builds neutral-atom tweezer-array and superconducting-qubit platforms for quantum computing, quantum error correction, and quantum sensing, aiming to combine the programmability of Rydberg arrays with new approaches to distributed and networked quantum sensing. The group is actively recruiting postdocs.

Lukin's group is a leading center for quantum science built on NV- and SiV-center diamond spin qubits, neutral-atom (Rydberg) tweezer arrays, and hybrid quantum networks, spanning quantum sensing, quantum information processing, and many-body physics. This work builds directly on the lineage of NV ensemble quantum sensing experiments (DEER, nanoscale NMR, T1 relaxometry) that first reached pT/√Hz-class magnetic sensitivities, which Lukin's own group helped pioneer and continues to extend toward nuclear-spin-register-based nanoscale NMR and distributed sensor networks.

Pfau's institute spans dipolar quantum gases (first Dy BEC, supersolids), interacting Rydberg atoms for simulation/computing, Rydberg electrometry with thermal atomic vapours and integrated atomic photonics, and laser cooling of molecules. Rydberg vapour electrometry is a leading electric-field quantum sensor. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work complements spin sensing with atom-based electric-field metrology.

Studies neutral-atom quantum computing and quantum optics with Rydberg atoms in optical tweezer arrays, including entanglement, nonlinear optics, and Rydberg-based electrometry/sensing.
