Stop the Myth (Score 1)

About half the comments here are on base; some of the others are way out in the weeds. Those who are interested in this topic might like my blog posting at Stop the Myth. It includes some links to some relatively sane analyses of what QKD will and will not be useful for. I do expect QKD to be useful at some point, but at the moment I expect its utility to be in restricted settings. Quantum repeaters are a long way off; they are one of my current research topics. They will be useful for general distributed quantum computation, as well as QKD.
