"At its core, the QRNG chip contains a light-emitting diode (LED) and an image sensor. Due to quantum noise, the LED emits a random number of photons, which are captured and counted by the image sensor’s pixels, giving a series of raw random numbers. These numbers are fed to a randomness-extraction algorithm which distills the entropy of quantum origin and makes it available to the user.
Based on a technology concept and patent from IDQ, and designed and manufactured by SK Telekom, the Quantum RNG Chip harnesses true quantum randomness from the shot noise of a light source captured by a CMOS image sensor"
