  • Abstract
    Quantum random number generators (QRNGs) have important applications in cryptographic protocols, games, and lotteries, among others. In contrast with software-based pseudorandom number generators, the number sequence generated is truly random. Most QRNGs found in the literature are based on single-photon sources and detectors. In this letter, we discuss the advantages and disadvantages of a QRNG that uses only one single-photon detector and weak coherent or thermal states as light source.
