Samsung and SK Telecom launched the Galaxy A Quantum in South Korea today. It is the world's first 5G smartphone with a quantum random number generator (QRNG) chipset, and it is exclusive to SK Telecom's network. The Galaxy A Quantum is a rebranded Galaxy A71 5G, and it is priced at KRW 649,000 (around $530).
The Galaxy A Quantum will be available for pre-order starting tomorrow. The phone will go on sale in Korea from May 22. Those who pre-order the phone will be eligible to receive the Galaxy Buds for free. Those who purchase the Galaxy A Quantum after the pre-order phase will get a KRW 50,000 (around $40) discount coupon to buy the Galaxy Buds.
The phone features the SKT IDQ S2Q000 QRNG chipset that was developed by SK Telecom's Switzerland-based subsidiary ID Quantique. It generators random numbers through quantum-crypto technology and creates secure keys that cannot be predicted, thus enhancing the security of the device.

How is the QRNG chipset used in the Galaxy A Quantum?
The SKT IDQ S2Q00, which is the world's smallest QRNG chipset (at 2.5mm x 2.5mm), uses an LED and a CMOS image sensor. It creates truly random numbers with unpredictable patterns. The CMOS image sensor is used to capture the quantum randomness from the image noise that is emitted by the LED.
The QRNG chipset enhances the security of various applications such as SK Pay, T ID login, and Initial. T ID is used for logging into various online services, including 11th Street, FLO, T Map, T membership, Wavve, Who, and others, and the service is used by over 19 million customers.
Initial is a blockchain mobile electronic certification service that is used to issue and submit various personal certifications without a need to reproduce a physical one. SK Telecom plans to expand the use of QRNG chipset and enhanced security for more services in the future. You can read more about the QRNG chipset works here.
