Randomness forms a crucial backbone of modern society, where every encryption key, secure transaction and digital signature ...

“This is a marvelous step” toward more efficient random number generation, says Rajarshi Roy, a physicist at the University of Maryland in College Park who was not involved in the work. Random number ...

Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment.

Researchers at ETH Zurich have developed a method to generate what they describe as ...

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 applications ...

Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could ...

Lotteries, accidents and rolls of dice — the world around us is full of unpredictable events. Yet generating a truly random series of numbers for encryption has remained a surprisingly difficult task.
