World’s First Perfect Randomness

June 8 , 2026 15 hrs 0 min 31 0
  • 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.
