It appears that the quantum crypto meme just won't go away.
Bob Gelfond of MagiQ promises us that for only $100,000, plus monthly
leasing of a dry fiber optic home run between your end systems, you
can have security that isn't even as good as what nearly free software
will give commodity computers over the unsecured public internet.
I wonder if this idea is ever going to die. My guess is it will, but
not until the people who have thrown away their money investing in
this technology go bankrupt.
Thanks for writing your note at the bottom. Quantum cryptography is a
fascinating thing, but first of all, it's not cryptography. It should
be called quantum secrecy, or something akin to that. Next, its
proponents have a tendency to effectively say, "Oh, math, that's
something that could go bad. But physics, *that* will always be good!"
