Dr. Nikolopoulos Georgios
Principal Researcher

Dr. Georgios Nikolopoulos received his PhD in 2001 from the University of Crete. His PhD work was focused on the dissipative dynamics of small quantum systems, which are coupled to continua that exhibit an unconventional density of states and do not allow for standard (e.g., Born and Markov) approximations. In 2003, after his military service, he moved to TU Darmstadt where he worked as a research associate in the framework of FP6 IP SECOQC project, which focused on the development of a global network for secure communication based on quantum cryptography.   Dr. Nikolopoulos joined IESL/FORTH as a Junior Researcher in 2007, and his research activities span a broad range of topics including quantum linear and non-linear optics, quantum communication, quantum cryptography, and ultracold quantum gases. In 2019 he was invited to particiapte in SFB CROSSING as a Mercator Fellow.
