We report on the planned experimental implementation of quantum key distribution on the campus of the Leibniz Universität Hannover. A fiber based continuous variable quantum cryptographic link will be established between the Albert-Einstein-Institute and the Institute of Quantum Optics, which are about 1 km apart. The link will be build with two-mode squeezed states at 1550 nm and standard telecommunication fibers. We present first experimental results concerning the generation of two-mode squeezing at 1550 nm. Furthermore the security of our scheme will be discussed and the expected secure key rates will be presented.
