The Fastest-Ever Random Number Generator Conjures Digits from Subatomic Noise in a Vacuum
• http://www.popsci.com, By Clay DillowTapping this spontaneous cascade of sub-atomic particles within vacuums, scientists at the Australian National University have built the world’s fastest random number generator by listening in on the action. Using lasers, the team has created a device that can listen to the random noise in the vacuum and use it to generate truly random numbers, which have myriad uses in encryption, information technology, computer modeling, and other complex tasks.
Most existing random number generators work off of some kind of computer algorithms. Those algorithms are pretty good, but if you know the inputs you can figure the outputs. In other words, the numbers aren’t truly random, they are just correlated in a way that is unknown to the user.
