it’s logic gates all the way down. This isn’t the first random-ish number generator that we’ve seen use shift registers. But if you’re looking for something that might actually pass some ...

It’s a field that need not be expensive or difficult to work in, as [Henk Mulder] shows us with his 4-bit analogue random number generator ... it has a bias towards logic one in its output ...

Fast randomness A diagram of the quantum random number generator on the photonic integrated chip. (Courtesy: Bing Bai and Yao Zheng) Smartphones could soon come equipped with a quantum-powered source ...

Lasers can generate random number sequences thanks to tiny, naturally occurring fluctuations in the light’s frequency over time. But using a laser beam to produce random numbers like that is ...
