The use of randomness is ubiquitous in our society, including jury pool selection, encryption of digital communications, and many other activities. However, in many applications, there is an incentive ...

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 ...

When you step inside Cloudflare's San Francisco office, the first thing you notice is a wall of lava lamps. Visitors often stop to take selfies, but the peculiar installation is more than an artistic ...

Although many physical processes appear random to us, it turns out to be challenging to produce high-quality randomness—bits for which it is guaranteed that no one can predict them 6,7. From a ...

Randomness is essential to some research, but it’s always been prohibitively complicated to achieve. Now, we can use “pseudorandomness” instead. Nothing is certain in the quantum realm. A particle, ...

Even the most modern random number generators do not produce perfectly random numbers, which can be a problem for cryptographic applications. ETH Zurich researchers use entangled superconducting ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can.

The 2023 Turing Award has been given to Avi Wigderson, a mathematician who discovered the strange connection between computation and randomness. Wigderson was announced the winner of the Association ...

The global economy needs true randomness to encrypt messages and make sure elections are honest. But not all randomness is random enough, and humans and computers alike are really bad at generating it ...
