ETH Zurich team generates certified perfect randomness (opens in new tab)

ETH Zurich researchers said they have generated mathematically certified perfect random numbers for the first time, using a quantum-physics protocol called randomness amplification. The work, published in Nature, turns imperfect random input into random bits whose unpredictability is certified through quantum measurements rather than assumptions about the devices producing them. The experiment used two superconducting quantum chips connected by a 30-meter cooled tube, with measurements based ...
