ETH Zurich scientists created a quantum “perfect die,” producing physics-certified randomness for cryptography and gaming.
Inside a 30-meter tunnel in Zurich, two qubits traded microwave whispers and out came numbers no machine could second-guess. An ETH Zurich team led by Renato Renner used entanglement and a two-source extractor to mint a stream of randomness that is c... [2967 chars]
