Not entirely clear how much demand there currently is for this but smartphone manufacturers are always looking for a differentiated angle, and if this drives a scaling of volumes for the specific QRNG chipset then that's never a bad thing.
The company claims that the phone, called the Galaxy A Quantum, has the world’s smallest quantum random number generator (QRNG) chipset that enhances data security on the device. SK Telecom added in a post that the QRNG chipset can generate unpredictable and patternless random numbers, which allows safer and more secure access to services like authentication and payments on their phones.
