Abstract
Random numbers are a fundamental resource in science and engineering with important applications in simulation and cryptography. The inherent randomness at the core of quantum mechanics makes quantum systems a perfect source of entropy. Quantum random number generation is one of the most mature quantum technologies with many alternative generation methods. We discuss the different technologies in quantum random number generation from the early devices based on radioactive decay to the multiple ways to use the quantum states of light to gather entropy from a quantum origin. We also discuss randomness extraction and amplification and the notable possibility of generating trusted random numbers even with untrusted hardware using device independent generation protocols.
That's the method described in https://arxiv.org/pdf/1604.03304.pdf on page 11: > A fast clock (down) is used to increase a counter. Whenever a detection is made (up), the counter is read and reset, generating one random number. > We restrict to a counter that generates values…
