Quantenkryptographie (19c3)

One of the fundamental laws of quantum mechanics, the Heisenberg uncertainty relation, tells us that every quantum measurement significantly influences the observed system. Thus Quantum Cryptography can guarantee secure communication between Alice (transmitter) and Bob (receiver). In our experiment we show that it is possible to perform Quantum Cryptography not only in laboratory demonstration experiments but also in a small and user friendly setup which can be used on everybodysw's desk for secure communication. about this event: http://www.ccc.de/congress/2002/fahrplan/event/382.en.html
