- Interesting article published in Physical Review A by Kim. et al.
on an experiment of a quantum attack to QKD. The results are in agreement with the theory, contrary to what it
would seem to come from the article on Nature.

At the March 2007 meeting of the American Physical Society has been presented the result of an experiment
to create QKD secret keys in free space at a distance of 144 km, this could be the first step towards
ground to satellite QKD.
