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. The difficulty lies ...

Two quantum chips linked through a 30-meter cooled tube enabled scientists to create certified perfectly random numbers.ETH Zurich Researchers at ETH Zurich have developed a method to generate what ...

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 ...
