Quantum Random Number Generator

TRL 6 help System/subsystem model or prototype demonstration in a relevant environment


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.


  • 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
