Description

Device-independent quantum key distribution aims to provide users with information-theoretically secure secret keys without any need for characterizing the physical devices. Nevertheless, there still exists a big gap between theory and experiments. In this work, we evaluate the performance of assisted device independent quantum key distribution in a realistic scenario, that is, using practical photonic sources and a finite number of signals exchanged between the two parties. For this task, we employ recently derived finite key rate formulas against general attacks. Our results are useful to analyze the feasibility of practical device-independent quantum key distribution.
