- Physicists at ETH Zurich, Switzerland, achieved the world's first certifiably perfect randomness using quantum entanglement.
- The breakthrough used entangled quantum bits (qubits) and Bell-test experiments to generate truly unpredictable random numbers.
- Researchers conducted over one billion trials in about nine hours to verify randomness.
- The method demonstrated randomness amplification, converting imperfect randomness into perfectly random outputs.
- Unlike conventional generators, the system is device-independent, relying on quantum behaviour rather than trusted hardware.
