The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random.

Here we present a simple experimental setup based on homodyne measurements that uses the purity of a continuous-variable quantum vacuum state to generate unique random numbers.

There’s no cheating this random number generator The protocol ensures jury duty selections and other draws are truly random and secure ...

Current methods of generating random numbers can produce predictable results. Researchers said the new method could generate higher-quality random numbers with less computer processing.

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.

In their office is a wall of 100 lava lamps monitored by cameras. The reaction of the lamps is unpredictable, and this allows them to generate really random numbers.

Many processes for producing these keys — such as the random number generator that's probably on your computer right now — use an algorithm that spits out a seemingly arbitrary string of numbers.
