(Phys.org) —A team of physicists led by Bruno Sanguinetti of the University of Geneva has found a way to use an ordinary smartphone as a true random number generator to provide secure communications.

“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 ...

Computers have trouble generating truly random numbers - but a new method could help A new method for computer-generating random numbers is being called "remarkable", and could help improve computer ...

A team of international scientists has developed a laser that can generate 254 trillion random digits per second, more than a hundred times faster than computer-based random number generators (RNG).
