As one of the top researchers in ultrashort-pulsed lasers for industrial applications, Prof. Dr. Andreas Tünnermann also focuses on the practical application of his scientific work in everyday life. By initiating and coordinating the research initiative QuNET, he pushes the boundaries of the emerging field of quantum communication towards a future implementation of the technology in real communication networks. As quantum communication enables a secure communication for the digital society of the future it is widely recognised as one of the key technologies for stable democracies.
