His scientific interests fall in the field of weak superconductivity (from tunnel spectroscopy to proximity effect, Josephson effect and Macroscopic Quantum Tunneling phenomena in moderately damped systems), superconducting qubits, new routes for the realization of superconducting qubits, Superconducting Single Photon Detectors for Quantum Communication, non-equilibrium superconductivity also in unconventional materials, advanced superconducting materials for quantum applications.
He is Scientific Coordinator of the Project “Development of quantum systems and technologies for cybersecurity in communication networks”, Italian Ministery of University and Research (2021-2023).
GPP is author of >170 publications on international journals and book chapters. He has given many invited talks at international conferences and research institutes.
