In the digital world, there is no such thing as a perfect roll of ...

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

Quantum random number generators (QRNGs) produce genuine randomness based on the inherent unpredictability of quantum mechanics. They have important applications in quantum information processing and ...

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 ...

Quantum random number generators find applications in both quantum and classical communications schemes, particularly in security protocols where they can be used as a source of random seed or key ...

Physicists have completed a study comparing the "randomness" in pi to that produced by random number generators. They have found that while sequences of digits from pi are indeed an acceptable ...

The prototype of a quantum random number generator is a single photon which impinges onto a beam splitter and is then detected by single photon detectors at one of the two output paths. Prior to ...

Good randomness is hard to find. John Graham-Cumming, programmer-turned-CTO of Cloudflare, found it in lava lamps. “It turns out that computers are really bad at generating random numbers. The only ...
