Samsung’s Galaxy Quantum 2 has built-in quantum cryptography

Samsung and South Korean carrier SK Telecom have announced Galaxy Quantum 2, Samsung’s second phone with built-in quantum cryptography technology for increased security. It is the sequel to last year’s Galaxy A Quantum.

The Quantum 2 contains a chip developed by a company called ID Quantique, which says it is the world’s smallest quantum random number generator (QRNG) at 2.5mm square. It works by capturing random noise with an LED and a CMOS image sensor. According to SK Telecom, the QRNG chip “enables smartphone holders to use services that require security in a more secure way by generating unpredictable and patternless real random numbers.”

Quantum Cryptography RNG is considered extremely challenging to hack without extensive physical access to a particular device. The benefits will seem pretty niche to the average customer, but the QRNG chip will automatically work with apps that use the Android Keystore APIs, which should make the technology more accessible to developers. SK Telecom praises local compatibility with Shinhan Bank and Standard Chartered Bank Korea, plus its own services such as T World. The carrier says it will work with more services in the future, including Samsung’s own credit cards.

The phone itself has fairly high specs, almost what you would have found in a high-end flagship phone from a year or two ago. It has a Qualcomm Snapdragon 855 Plus processor, a 64-megapixel camera and a 6.7-inch 120Hz OLED display.

The Galaxy Quantum 2 is currently only confirmed for release in South Korea. It will go on sale on April 23.
