HL 26: Focus Session: Quantum light sources for applications in quantum communication networks

Mittwoch, 3. April 2019, 09:30–13:00, H34

The present focus session aims at discussing current state-of-the-art of non-classical light sources which can be found compatible with short- (few meters), mid- (few kilometers) or long-distance (several tens of km) quantum networks. Different approaches for the generation of non-classical light will be discussed, both experimentally and theoretically. We aim at stimulating the discussion on advantages and limitations of these approaches and under which aspects they can be find promising.
