Stefano Paesani

Stefano Paesani is an Associate Professor at the University of Copenhagen, affiliated with the Niels Bohr Institute (Department of Quantum Optics) within the Faculty of Science. His research focuses on quantum photonics, quantum computing, and integrated photonic systems. He explores scalable quantum architectures leveraging quantum emitters and graph states, with a particular emphasis on error correction, photonic nonlinearity, and high-dimensional entanglement.

His work includes developing fusion-based photonic computing schemes, optimizing loss-tolerant architectures, and advancing programmable silicon-nitride integrated circuits for quantum information processing. Recent contributions address deterministic photon source interfacing, reconfigurable nonlinear circuits, and high-speed lithium niobate processors. His research also intersects quantum machine learning and Hamiltonian learning, utilizing quantum systems to model complex physical phenomena.

Stefano collaborates with interdisciplinary teams across the University of Copenhagen’s Quantum Hub, contributing to initiatives in quantum communication, quantum simulation, and quantum sensing. His experimental setups often involve solid-state quantum emitters and advanced photonic platforms, aiming to bridge theoretical models with practical quantum technologies.
