The birth of the world's first quantum security 5G phone powered by a quantum random number generator (QRNG) chipset dates back to 2016 when SK Telecom's Quantum Lab made a sudden proposal. The Galaxy A Quantum smartphone debuted in May this year after four years of development efforts by SK Telecom and fabless (semiconductor design) company Betree. It is now the top seller among budget 5G smartphones in Korea.


Betree held a news conference on June 11 to give a detailed account of how the world's first QRNG chipset for mobile devices was commercialized and found its way into Samsung Electronics' smartphones.

SK Telecom and Samsung Electronics agreed at CES 2020 held in January to cooperate in installing a QRNG chipset on a smartphone. Before that, SK Telecom had helped Betree commercialize the chipset.

A QRNG chipset creates unpredictable and patternless pure random numbers, helping smartphone users enjoy certain services without worrying about security.

The chipset has evolved from a prototype in the form of a USB device in 2016 to the current ultra-small chipset. Betree commercialized the world's first 2.5 x 2.5 x 0.8 mm mobile QRNG chipset in 2018 by drastically reducing the chipset size and passed Samsung Electronics' quality standards. Mass-production of the chipset started in April 2020.

SK Telecom is planning to increase its lineup of smartphones loaded with quantum security technology by supplying QRNG chipsets for mobile devices to global smartphone manufacturers.
