Image Sensor as Quantum Random Number Generator

Medium.com: A group of researchers from Geneva University, Switzerland, proposes to use image sensor as a high quality quantum random number generator, widely used in cryptography, security and other applications: "Quantum random number generation on a mobile phone" by Bruno Sanguinetti, Anthony Martin, Hugo Zbinden, Nicolas Gisin. The principle of their work in explained in the figure below. The random number quality has passed a number of tests for randommness.
