the_newsbeagle writes "This article discusses a proposal to create cash that can't be counterfeited by embedding quantum particles in banknotes. A counterfeiter trying to copy a real bill would have to precisely measure all the attributes of the embedded quantum particles — which is impossible under the tricky laws of quantum mechanics (PDF). MIT computer scientist Scott Aaronson, who famously offered a prize for anyone who could prove quantum computers are impossible, said, 'This is science fiction, but it’s science fiction that doesn’t violate any of the known laws of physics.'"
