Advantage distillation for device-independent quantum key distribution
(2019)arXivWe derive a sufficient condition for advantage distillation to be secure against collective attacks in device-independent quantum key distribution (DIQKD), focusing on the repetition-code protocol. In addition, we describe a semidefinite programming method to check whether this condition holds for any probability distribution obtained in a DIQKD protocol. Applying our method to various probability distributions, we find that advantage ...Working Paper -
How do bike types and cycling frequency shape cycling infrastructure preferences?
(2023)Arbeitsberichte Verkehrs- und RaumplanungWe examine the difference in preferences among different cyclist groups, being the first to examine differences in cycling infrastructure preferences among s-pedelec, e-bike and conventional bike riders. We also examine how the cycling frequency of individuals shapes these preferences. To do so we develop a stated-preference choice experiment varying cycling infrastructure and car traffic features impacting cycling for both main and ...Working Paper
