Towards Device-Independent Quantum Key Distribution with Photonic Devices
Corentin Lanore, Xavier Valcarce, Jean Etesse +2
Quantum Key Distribution (QKD) protocols enable two distant parties to communicate with information-theoretically proven secrecy. However, these protocols are generally vulnerable…

Adrian Holzäpfel, Jean Etesse, Krzysztof T. Kaczmarek +3
Quantum memories with long storage times are key elements in long-distance quantum networks. The atomic frequency comb (AFC) memory in particular has shown great promise to fulfill…
