It’s quantum, it’s chaotic, it makes for a great source for a random number generator, and there are already dozens of prototype circuits around the Internet.

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 ...

There are many ways to generate random numbers, the most well-known of which can be traced back over thousands of years: for instance, a simple dice, or coin-flipping, provides unpredictable results.

Random number generation is the Achilles heel of cryptography. Intel's Ivy Bridge processor incorporates its own, robust random number generator.

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.
