Computers are known to be precise and — usually — repeatable. That’s why it is so hard to get something that seems random out of them. Yet random things are great for games, encryption, and multimedia ...

Randomness is a slippery concept, defying precise definition. A simple example of a random series is provided by repeatedly tossing a coin. Assigning “1” for heads and “0” for tails, we generate 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 ...

Need a random number? Sure, you could just roll a die, but if you do, you might invite laughter from nearby quantum enthusiasts. If it’s truly, unpredictably random numbers you need, look no farther ...

Nobel Prize-winning physicist Frank Wilczek explores the secrets of the cosmos. Read previous columns here. Many summers ago, I discovered a book called “A Million Random Digits with 100,000 Normal ...

You indirectly use random numbers online every day—to establish secure connections, to encrypt data, perhaps even to satisfy your gambling problem. But their ubiquity belies the fact that they’re ...

Mathematicians concerned with cryptography need novel ways of generating random numbers in order to securely transmit data such as a credit card number or especially private email. But it's hard for ...

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 ...

Random numbers are essential for secure cyber communications. But making truly random numbers is harder than it seems. Now scientists have devised a way to make the most random random numbers ever. A ...
