Abstract
In this letter, we present an implementation of a random number generator based on photon polarization superposition. We prepare photons in a superposition state of vertical and horizontal polarizations, let them pass through a polarizing beamsplitter and set two detectors at each path to get a 50–50 chance of finding the photon at each detector. We present the results of the NIST test suite for random number generators for our binary sequence of approximately 1.4 × 107 bits and analyze the different p -values obtained to statistically assess its randomness. In doing so, we use von Neumann’s algorithm for bias removal and briefly explain how the statistical tests work.
