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, ...

Andreas Wallraff and Renato Renner (f.l.t.r.) next to the 30-meter link connecting two quantum chips. Using this experiment, ETH researchers generated certified perfect randomness for the first time.

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 ...

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 ...

A team including Scott Aaronson demonstrated what may be the first practical application of quantum computers to a real world problem. Using a 56-qubit quantum computer, researchers have for the first ...
