Laboratory of Theoretical Physics of Nanosystems

The Laboratory of Theoretical Physics of Nanosystems (LTPN) at EPFL, led by Prof. Vincenzo Savona, focuses on quantum optics, many-body open quantum systems, quantum information, and quantum computing. Research includes studying open quantum systems influenced by the environment, developing quantum error correction codes, and simulating quantum computing platforms. The lab explores emergent phenomena like dissipative phase transitions and develops efficient numerical methods based on tensor networks and quantum Monte Carlo. Additionally, LTPN models artificial photonic nanostructures using smart modal expansion, global optimization algorithms, and machine learning, achieving world records in photonic crystal cavities and slow light in waveguides.
