Exploiting noise in quantum computers
Noise is generally considered to be a bad thing in a quantum computer, in any electronic system in fact. A group of researchers in Europe and the US has figured out a way to exploit this noise to implement cryptographic protocols between two parties, without resorting to assumptions about factoring or relying on a trusted third party. This can even be done using the quantum cryptography hardware that is available on the market today. Maybe one day we'll use quantum identification to withdraw money from an ATM with our cards. First we'll have to equip our debit cards with freakin' laser beams though...

I didn't, but I know some of the people very well. I'd like it posted on mefi proper, but that's not the idea if you know the people who worked on it. Right?
Or am I wrong? I wasn't sure...
