Quantum Crypto

Nice little article from the BBC today about a practical realization of quantum cryptography.

I particularly liked the line where they conclude that maybe God does play dice!

I don't have the time to write much more, but I will add one thing. Over many years, the most amazing thing about quantum mechanics has been the way it has passed experimental tests of the most arcane predictions. I say that not only because these tests confirm some rather odd physics, but because simply doing them at all has taken truly outstanding skill on the part of experimental physicists.
