Lotteries, accidents and rolls of dice — the world around us is full of unpredictable events. Yet generating a truly random series of numbers for encryption has remained a surprisingly difficult task.

A new network paradigm can generate meaningfully random numbers—and fast. In network encryption, randomness has huge value because it’s not “solvable” by hackers. Classical computers can’t be ...

Isn't it ionic: An artist's representation of Quantinuum's 56-qubit trapped-ion quantum computer. Researchers used this computer to demonstrate a way of generating random numbers, then using a ...

If it hadn’t been for a shortfall in the supply of random numbers, one of history’s most infamous spy rings might never have been exposed. The shortage occurred in late 1941, two years after the start ...

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 ...
