Certified perfect randomness achieved for the first time (ethz.ch)

• First-ever certified perfect random numbers generated using quantum entanglement
• Improved Bell test with superconducting qubits over 30-meter distance
• Potential to become a standard for cryptographic security and digital infrastructure

"Researchers at ETH Zurich have, for the first time, created certifiably perfect random numbers using a quantum experiment. By entangling two superconducting qubits over 30 meters and performing an improved Bell test, they amplified imperfect randomness into perfect randomness. The result, published in Nature, could underpin future cryptographic security."
