Researchers Say They’ve Achieved Perfect Randomness
AI-summarised brief · reviewed before publication
Researchers at ETH Zurich have successfully demonstrated a method to generate mathematically certifiable perfect randomness using entangled quantum bits and an advanced Bell test. The team used two superconducting qubits connected by a 30-meter cryogenic link and combined imperfect random inputs with quantum measurements and specialized algorithms to amplify weak randomness into fully random sequences. This breakthrough addresses a long-standing challenge in cryptography and digital security, with potential applications in encryption, quantum-secure communications, blockchain systems, and lotteries.
