One-sided DI-QKD secure against coherent attacks over long distances
One-sided DI-QKD secure against coherent attacks over long distances
Quantum Key Distribution (QKD) is a technique enabling provable secure communication but faces challenges in device characterization, posing potential security risks. Device-Independent (DI) QKD protocols overcome this issue by making minimal device assumptions but are limited in distance because they require high detection efficiencies, which refer to the ability of …
