It may be a decade or more before quantum computers become common enough that we’ll find out whether “post-quantum cryptography” will stand up to genuine quantum computers. In the meantime, some ...

While world events are often difficult to predict, true randomness is surprisingly hard to find. In recent years, physicists have turned to quantum mechanics for a solution, using the inherently ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

Nanoscale device employs magnetic tunnel junctions to convert thermal noise into binary signals for random number generation.

Researchers at Japan’s Nippon Telegraph and Telephone Corporation (NTT) have built a quantum random number generator (QRNG) that delivers random bits periodically with high speed and is robust against ...

Research presented at the Black Hat security conference in Las Vegas, Nevada, last week revealed that the Linux software used by the most widely used random-number generators does not spit out ...

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 ...

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 ...
