Quantum Random Number Generator

Researchers at The Australian National University have developed the fastest random number generator in the world by using the quantum fluctuation in the vacuum, and put it online.

The researchers from the ANU ARC Centre of Excellence for Quantum Computation and Communication Technology have used very sensitive light detectors to listen to vacuum.

Quantum mechanics says that vacuum is not empty but has virtual sub-atomic particles spontaneously appearing and disappearing, which gives rise to quantum random noise. That noise can be used to generate billions of random numbers per second and their unpredictability is guaranteed by quantum theory.
