South Korean Researchers Develop World’s Smallest Chip for Beta Quantum Random Number Generators

By IQT News posted 09 Sep 2021

(AJU.Daily) Researchers from South Korea’s two leading state research bodies have developed a core chip for quantum random number generators that provide true random numbers at high speed to fundamentally prevent hacking. They opened the path for commercialization by miniaturizing a beta quantum random number generator into a 1.5mm chip.
A joint research team from the state-run Korea Atomic Energy Research Institute (KAERI) and the Electronics and Telecommunications Research Institute (ETRI) would try to maximize the performance of beta quantum random number generator chips and promote commercialization for use in the cryptographic communication market for small Internet of Things.
“If this technology is commercialized, it will be the ultimate truce random number generator that can be installed in all types of computers, security systems, processors, and IoT modules,” ETRI head Kim Myung-joon said in a statement on September 9.
KAERI said that the joint research team has integrated key circuits that generate random numbers from nickel-63 beta rays into the world’s “smallest and fastest” beta quantum random number generator that can supply hacking-free random numbers to cryptographic security systems for IoT. Nickel-63 has a low energy beta spectrum and reasonably long half-life.
