Principles of quantum cryptography/quantum key distribution (QKD) using attenuated light pulses

H. Weinfurter,    LMU Munich, Germany


Based on the very foundations of quantum physics, quantum information methods can enhance conventional communication methods and enable completely new types of information processing. Quantum cryptography or, more precisely, quantum key distribution is the first application that enables communications to be made secure against eavesdropping attacks. This chapter gives an overview of the principle of the method and of how to implement this method based on attenuated laser pulses.
