RANDOMNESS IS A valuable commodity. Computer models of complex systems ranging from the weather to the stockmarket are voracious consumers of random numbers. Cryptography, too, relies heavily on ...

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 ...

Many popular random number generators (RNGs) are based on classical computer algorithms and have the advantage of being fast and easy to implement. The best examples pass many statistical tests ...
