The randomness in quantum physics is imperfect and needs amplification to be considered truly random, the researchers say.

Perfect randomness sounds simple, until you try to make it. A die can be polished, balanced and rolled thousands of times.

ETH Zurich scientists for the first time created certified perfect random numbers using entangled quantum chips.

Random number generators have been around for ages, but they often have subtle imperfections that cause patterns to emerge.

Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal ...
