Unconditional security proofs of various quantum key
distribution (QKD) protocols are built on idealized
assumptions. One key assumption is: the sender (Alice) can
prepare the required quantum states without errors. However,
such an assumption may be
While I'm quite skeptical that QKD will prove of practical use, I do think it's
worth investigating. The physics are nice, and it provides an interesting and
different way of thinking about cryptography. I think that there's a
non-trivial chance that it will some day give us some very

I agree. What I don't understand is why people are trying to
*commercialize* it, or claiming that it is of practical use as it
stands.

Second, you can't use QKD on a computer network. It is strictly point to
point. Want 200 nodes to talk to each other? Then you need 40,000
fibers, without repeaters, in between the nodes, each with a $10,000 or
