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.

Directions: (1) tr-ARPES and ultrafast spectroscopy of non-equilibrium electronic dynamics in TMDs and graphene heterostructures; (2) 2D material nanophotonic devices for light sensing and emission; (3) wafer-scale CVD growth of hBN, MoS2, WSe2 for integrated quantum devices; (4) scanning probe characterization of local optical and electronic properties. Key tool: time-resolved photoemission as ultrafast electronic structure sensing.
Parkinson's group uses ultrafast optical spectroscopy to study carrier dynamics in photonic materials with quantum device applications. Research directions: (1) Time-resolved photoluminescence — TRPL with single-photon counting to map exciton lifetimes, diffusion, and defect trapping in GaN, perovskite, and 2D semiconductor quantum wells; (2) Optical single-particle spectroscopy — isolating single nanowires or nanocrystals for defect-free measurements of intrinsic optical properties; (3) Photon-number statistics — Hanbury Brown–Twiss measurements of single-photon purity from quantum dots and localized excitons; (4) Semiconductor quantum sensing interfaces — studying how carrier dynamics affect the fidelity of semiconductor-based quantum sensors and emitters.

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.
