Researchers in Switzerland claim to have built a perfect random number generator from two quantum superconducting chips, a 30-meter-long pipe, and some software. The resulting device could be used to ...

Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing ...

Perfect randomness sounds simple, until you try to make it. A die can be polished, balanced and rolled thousands of times. Yet, one face may still land up a little more often than the others. In daily ...

Researchers have, for the first time, created certifiably perfect random numbers using a quantum experiment. These can be used, for instance, for encrypting messages. (Nanowerk News) Creating perfect ...

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 ...
