some researchers from the University of Vienna have reportedly transferred money from a bank to Vienna City Hall using a process secured by quantum cryptography.
from what i've heard, this is the first real, publicized use of quantum crypto that uses single photons. read the article for some details, and if you're interested, check out The Feynman Processor by Milburn and Davies for more info on what the heck quantum crypto is. i have a copy, you can borrow it. also check out these other links
why should you care? there are already secure bank transfer mechanisms. well not quite like this. this is really the only provably secure (besides one-time pads) system for data transfer over public channels. everything else is just really close to totally secure ;)
