On /. today:
An anonymous reader writes with today's announcement that "the Austrian
project for Quantum Cryptography[1] made the world's first Bank Transfer
via Quantum Cryptography Based on Entangled Photons; see also
Einstein-Podolski-Rosen Paradoxon[2]." (For more background, see the
recent Slashdot post "Quantum Cryptography Leaving the Lab."[3])

I have to agree with Perry on this one: I simply can't see a compelling
reason for the push currently being given to ridiculously overpriced
implementations of what started off as a lab toy, and what offers - in
all seriousness - almost no practical benefits over the proper use of
conventional techniques. Besides, any of the ultrasecret applications
that *might* (I remain very skeptical) call for such a level of
confidentiality - things like military communication or diplomatic
message exchange between a country and its ambassadors - are all too
likely to be out of the range currently offered by these QC setups (last
I read, if I'm not mistaken, it was about 50 km or ~30 miles). Fine, the
range might improve - but I doubt that the amount of money and hassle
required to set these up will.
Cheers,
Ivan
