Quantum key distribution on Hannover Campus: Theory — •Jörg Duhme, Torsten Franz, and Reinhard Werner — Institut für theoretische Physik, Leibniz Universität Hannover

We report on an upcoming implementation of quantum key distribution on LUH campus, see talk by V. Händchen et al. The theoretical model for the experiment includes different noise sources, e.g. damping and phase noise. We discuss the security and expected secure bit rates and comment on the problem of extending security proofs from collective to coherent attacks for continuous variable key distribution.
