Quantum Random Number Generator


SK Telecom has developed a prototype of Quantum Random Number Generator, which is small enough to be used for diverse electronics devices including self-driving cars, smartphones and drones to prevent them from being hacked.

Quantum, which is the minimum amount of any physical entity involved in an interaction, has features of not being duplicated, making it usable for next-generation security technology. The Quantum Random Number Generator, the carrier said, can consistently create a “true random number,” which cannot be predicted and has no consistent pattern, according to the firm.


TRL 6: System/subsystem model or prototype demonstration in a relevant environment Representative model or prototype system, which is well beyond that of TRL 5, is tested in a relevant environment. Represents a major step up in a technology's demonstrated readiness. Examples include testing a prototype in a high-fidelity laboratory environment or in a simulated operational environment.

  • based on the non-deterministic properties of quantum physics (mostly, quantum optics)
  •  easy to understand the origin of randomness
  •  high-quality and high-speed
  • but large and complicated a little bit
