The state of the art of quantum key distribution. — •Hugo Zbinden — University of Geneva, Switzerland
I will give a short introduction into Quantum Key Distribution, which could play an important role in future secure communications. Some experimental challenges, in particular for QKD over long distances and at high rates are discussed. I will present a recent experiment of QKD over 400km of optical fibre and options for increasing this distance using quantum repeaters or satellites.
