this quantum random number generator can never be hacked

lotteries, accidents and rolls of dice — the world around us is full of unpredictable events. yet generating a truly random series of numbers for encryption has remained a surprisingly difficult task. now, researchers have used a mind-bending experiment relying on both albert einstein's theory of relativity and quantum mechanics, which describes the probabilistic nature of subatomic particles, to produce strings of numbers that are guaranteed to be random. "if you sent in some team of people to examine our experimental components as closely as they wanted and then have them try to come up with a prediction for what these random numbers would be afterwards, there's just no way they could predict them," study co-author and mathematician peter bierhorst of the national institute of standards and technology (nist) in boulder, colorado, told live science. [the world's most beautiful equations] computers everywhere use random numbers as keys to lock or unlock encrypted information. many processes for producing these keys — such as the random number generator that's probably on your computer right now — use an algorithm that spits out a seemingly arbitrary string of numbers. other approaches try to make use of real-world randomness, for instance measuring the length of time between keystrokes or the fluctuating temperature of a computer server, to produce random numbers. but such methods are still susceptible to attack. savvy hackers can either tamp...
