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
