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.

From jury duty to tax audits, randomness plays a big role. Scientists used quantum physics to build a system that ensures those number draws can’t be gamed.
