Quantum Coin Toss
Abstract:
Our financial world operates on the basis of encrypted computer systems, but increasingly computers are getting advanced enough that such systems may not remain secure for long. Part of the problem is that "random number generators" in computer systems really don't generate random numbers ... they just use a variable process to create a number. A sophisticated enough computer system could, in theory, figure out what "random" number another computer is generating. Physicist Antonio Acin of Spain's Institute of Photonic Sciences believes he's come up with a process that can help - use quantum processes to generate genuinely random numbers.
