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

Researchers at ETH Zurich have developed a method to generate what they describe as ...

Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could strengthen cryptography and other security systems.

Sometimes you need random numbers — and properly random ones, at that. Hackaday Alum [Sean Boyce] whipped up a rig that serves up just that, tasty random bytes delivered fresh over MQTT. [Sean] tells ...

Randomness rules the very fabric of reality. So it only makes sense that scientists have figured out how to use nature’s randomness as a tool in our mundane world. Random numbers go hand-in-hand with ...

There will be an app for that: making random numbers on a mobile phone. (Courtesy: Marketa Michalkova) Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries ...

Using the inherent quantum flickering of empty space, researchers have figured out how to generate random numbers at an unprecedented rate. The record-breaking method could be used to enhance ...

Your job is to create a random number generator. Your device starts with a speaker and a membrane. On this membrane will sit a handful of small, marble-size copper balls. An audio source feeds the ...
