Researchers at ETH Zurich, led by Renato Renner, have developed a novel device termed a 'perfect die.' This creation utilizes quantum entanglement by linking two qubits through a 30-meter tunnel using microwave photons. The output is further refined by a two-source extractor. The unpredictability of the generated random numbers is certified by the fundamental laws of physics, surpassing classical random number generators. Published in Nature, the findings suggest significant potential applications in fields such as cryptography and gaming, where true randomness is crucial.
