Random thought of the day: "We need quantum key distribution for secure networks, because the Chinese already have it and we cannot fall behind the Chinese!!"

My dude. By definition these things have incredibly short range, since you can't have amplifiers/repeaters in the middle. I don't know where in China you think they're using that, but I almost guarantee that it's secure against interception because you can't get to it, because there's so much China around it, not because of Funky Physics.
