With this new series of online talks we start to address challenges in the research fields where the IQCC is playing a role, through the investigations of one of the Principal Investigators. An external expert is invited to give a seminar, together with one of the junior researchers of the IQCC. These complementary views will highlight the current state-of-the-art on that topic, discuss possible bottlenecks and how they are being solved, and will provide an outlook into the future.
