One of the hardest things to do in physics is to generate true, provably unpredictable randomness. That's because it's impossible to determine randomness based on the output alone. Dice may have nicks ...

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 ...

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 ...
