Cloudflare is one of those Internet companies you use all the time, but don’t usually know it. Big websites you visit use Cloudflare to shore up their defenses against denial of service attacks. The ...

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 ...

Randomness rules the very fabric of reality. So it only makes sense that scientists have figured out how to use nature’s randomness as a tool in our mundane world. Random numbers go hand-in-hand with ...

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 ...

Whether it’s a game of D&D or encrypting top-secret information, a wide array of methods are available for generating the needed random numbers with high enough entropy for their use case. For a ...

Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random ...

“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 ...

Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. Whether for use in ...

If your name gets picked for jury duty, it’s because a computer used a random number generator to select it. The same goes for tax audits or when you opt for a quick pick lottery ticket. But how can ...
