Title: The Smooth Entropy Formalism on Operator Algebras and
Applications to the Security Analysis of CV Crypto Schemes
Speaker: Volkher Scholz (ETH Zurich)
Abstract:
We discuss the extension of the smooth entropy formalism to
arbitrary physical systems with no bound on the number of degrees of
freedom, comparing them with already existing notions of entropy for
infinite-dimensional systems. Our analysis is both conceptual as
well as based on operational primitives, for example we ask for the
ability to perform privacy amplification against any kind of quantum
side information. As an application, we show how to employ a
version of the entropic uncertainty relation to provide a security
analysis for continuous variable quantum key distribution protocols.
