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.
