ETH Zurich has demonstrated a practical method for certifying perfect randomness by using entangled superconducting qubits separated by 30 meters to prevent light-speed information exchange. This randomness amplification technique overcomes inherent biases in conventional generators, offering a critical foundation for robust encryption and quantum-resistant communication systems. The breakthrough validates the necessity of physical separation in quantum setups to ensure cryptographic integrity.

Bell-Test Enables ETH Zurich to Create Truly Random Numbers
Quantum Zeitgeist3 min read
ETH Zurich researchers achieved certifiably perfect random numbers via a quantum experiment, utilizing a Bell-test with entangled superconducting.
Researchers at ETH Zurich have created certifiably perfect random numbers using a quantum experiment that could underpin future secure encryption methods. The team, led by Renato Renner and Andreas Wallraff, overcame the challenge of inherent imperfections in existing random number generators by employing entangled superconducting qubits and a refined “Bell-test.” This technology amplifies imperfect randomness into a truly random sequence, a feat demonstrated…
