Device-independent randomness amplification demonstrated with superconducting qubits
Researchers demonstrate device-independent randomness amplification by performing a loophole-free Bell test on superconducting circuits, achieving high Bell violation and a fast trial rate to convert weak, imperfect randomness into high-quality randomness—an outcome impossible to achieve classically. The work includes publicly available data and code from ETH Zurich and advances quantum randomness generation with implications for cryptography and quantum information processing.
