Samsungs Galaxy Quantum 2 has quantum cryptography built in

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

The Quantum 2 includes a chip developed by a company called ID Quantique, which says it’s 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 “allows smartphone holders to use services that require security in a more safe and secure manner by generating unpredictable and patternless true random numbers.”

Quantum cryptography RNG is considered to be extremely challenging to...
