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.

While the outcome is always random when measuring a single particle, a pair’s properties are more correlated than classical physics dictates.

But the random number generator they built was, they reasoned, still useful. So Haahr made it public at random.org, where it has been churning out random numbers ever since. It gets a lot of visitors.

Even if a random number generator used seemingly random processes in nature, it would be hard to verify that those numbers are truly random, Shalm added.

Professor Jooyoung Lee stated, "POSDRBG is a new deterministic random bit generator that improves both random number generation speed and security, making it applicable from small IoT devices to ...
