taking quantum theory to the bank

Nature magazine has an article on the first secure money transfer using entangled protons for quantum cryptography.

In last week’s trial, the entangled photons were created in a branch of the Bank of Austria in Vienna. One was sent to the city hall through a 1,450-metre-long fibreglass cable. The transfer took 90 seconds to complete; the money was then donated to Zeilinger’s lab.

That’s scary-cool.
