    "abstract": "We demonstrate a prototype-implementation of deterministic information\nencoding for quantum key distribution (QKD) following the ping-pong coding\nprotocol [K. Bostroem, T. Felbinger, Phys. Rev. Lett. 89 (2002) 187902-1]. Due\nto the deterministic nature of this protocol the need for post-processing the\nkey is distinctly reduced compared to non-deterministic protocols. In the\ncourse of our implementation we analyze the practicability of the protocol and\ndiscuss some security aspects of information transfer in such a deterministic\nscheme.",
