In the Swiss experiment, the camera was used to create a 1.25 Gbit/s stream of random numbers. One worry about any random-number generator is that the numbers could be influenced in a predictable way ...

These initial random results necessitated months of refinement and only ran for a few hours in total. Even then, the physicists and engineers only generated 512 bits of true randomness.

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in ...
