Compact quantum random number generation using a linear optocoupler
Random number generation (RNG) is a primitive operation that is required in many contexts such as scientific simulations, computational statistics and of course cryptography. Given the crucial role it plays in security, hardware RNGs are preferred to pseudo-random algorithms. The key difference between the two is that hardware RNGs rely on physical effects to produce random numbers, and therefore they are more secure. In their work, Yingying Hu and colleagues have created a simple and fast hardware RNG that relies on the random recombination of charges and holes in a light emitting diode. The samples are recorded at 43 Mbps, and they pass with flying colors the NIST-STS test suite for random number generators. Small size RNGs like the one in this work could be embedded in IoT devices, wearable devices and virtually any device where size is of the essence.
