Abstract

Quantum key distribution (QKD) is a maturing technology that has evolved from an abstract idea to practical systems that are even commercially available. In QKD, we have learned this the hard way, when it was realized that some devices could actually be hacked, not because the theory was wrong, but because a practical device is always much more complicated than even the most elaborate security proof. While keeping the security aspect under control, experimenters want to optimize their systems so that they can deliver the highest secure key rate possible under the conditions of a chosen quantum channel.
