Scientists Use Quantum Entanglement to Create Perfect Random Numbers
- On Wednesday, ETH Zurich Researchers published a study in Nature detailing a new method to generate "perfect" random numbers using a two-qubit quantum system.
- Conventional electronic devices rely on deterministic logic, making output predictable to adversaries; the team developed "randomness amplification" to transform imperfect randomness into certified perfect randomness.
- The experiment used two superconducting quantum chips connected by a 30-meter-long cooled tube, where researchers applied a Bell test to verify the system and ensure randomness is certifiable.
- Renner, a physics professor at ETH Zurich, said the resulting sequence of zeros and ones is "really perfectly random," demonstrating outcomes that are now certifiable.
- The work may support future quantum-secure communication networks, as experts believe this could eventually serve as a trusted source of randomness for secure digital systems, like atomic clocks provide certified timekeeping.

Scientists use quantum entanglement to create perfect random numbers
Researchers at ETH Zurich have developed a method to generate what they describe as “perfect” random numbers using quantum physics, a breakthrough that could strengthen encryption systems and digital security tools. The team created the system using two superconducting quantum chips connected by a 30-meter-long cooled tube. The setup allowed the researchers to generate certified random numbers by exploiting quantum entanglement, where measuremen…
Perfect randomness realized for the first time
Creating perfect randomness is surprisingly difficult. Even modern random number generators never generate completely ideal random numbers: small systematic errors can result in some numbers appearing slightly more frequently than others. For many applications, this does not matter. In cryptography, however, even the tiniest deviations can be problematic.
Physicists at ETH Zurich have for the first time managed to produce perfectly random numbers. Now they want to sell the chance. But does anyone need that?
