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 ...

Using the inherent quantum flickering of empty space, researchers have figured out how to generate random numbers at an unprecedented rate. The record-breaking method could be used to enhance ...

It’s easy to return random values in Microsoft Excel, but returning random letters might leave you scratching your head. Fortunately, you only need two functions. Excel provides three functions for ...

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 ...

A quantum random-number generator has been developed that uses classical cryptography to certify that its output was produced by a quantum process. A truly random number is generated by a process ...

Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also ...

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

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 ...

Scientists have developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in ...
