Quantum key distribution with finite resources: calculating the min-entropy — •Sylvia Bratzik, Markus Mertz, Hermann Kampermann, Silvestre Abruzzo, and Dagmar Bruß — Heinrich-Heine-Universität, Universitätsstr.1, 40225 Düsseldorf

The min-entropy is an important quantity in quantum key distribution [1]. Recently, a connection between the min- entropy and the minimal-error discrimination problem was found [2]. We use this connection to evaluate the min-entropy for different quantum key distribution setups.
