The first live demonstration of a working quantum key distribution (QKD) network will take place in Vienna between 8th October 2008 and 10th October 2008 in the framework of the SECOQC international conference.

Seven QKD-links will be combined in a novel quantum-back-bone network physically deployed within a typical metropolitan area network to connect different company sites from SIEMENS Austria. Typical applications for QKD, to secure data traffic from telephony and video conferencing, will also be included in the demonstration.


The appeal of quantum cryptography is that its security is based on the laws of nature. In contrast to existing classical schemes of Key Distribution, Quantum Key Distribution does not invoke the transport of the key, since it is created at the sender and receiver site immediately. Furthermore, the key is created from a completely random sequence, which is in general an extremely diffcult task in classical schemes. Finally, eavesdropping is easily detected due to the fragile nature of the qubits invoked for the quantum key distribution.

Conference-Announcement Einsteins in the city II :: Oct 30-31, 2007
An International Student Research Conference at The City College of New York. Stefan Schauer of the ARC will give a talk on QKD. "We will discuss a QKD protocol by Li et al. based on entanglement swapping [J. Opt. B: Quantum Semiclass. Opt., 5(2), 155--157, 2003] and show that it is open to a special type of attack using the same technique. An adversary will be able to obtain full information about the key without being detected. Additionally, we will give some ideas on how such protocols can be secured from this kind of attack strategy."
