 QRN: Quantum Random Number Generator Theory of operation Summary The Quantum Random Number Generator (QRNG), designed by Micro Photon Devices (MPD) shown in Figure 1 and named QRN, is a physical generator of random numbers based on the intrinsic randomness of quantum optical processes. The device exploits the stochastic number of detected photons within a fix observation time, in order to generate a random bit stream. The detection and processing of the photons is performed by a CMOS chip which includes 1024 independent Single Photon Avalanche Diodes (SPAD) [1] and achieves random bit generation rates of 16, 32, 64, 128 and 200 Mbit/s, depending on the device grade. MPD has verified the absolute randomness of the generated random data with standard statistical test suites and more stringent correlation and bias tests. In all cases, the data generated by the QRN passed the applied tests. Introduction Different applications require the generation of high quality random number sequences, such as Cryptography, Monte Carlo numerical simulations and image processing [2] [3] [4] [5], just to mention a few. Cryptography, for example, aims to keep messages safe. A private message, sent via physical media in form of electromagnetic waves or electrical signals, must be read only by the recipient it is addressed to. The degree of security of the message depends on the cipher and the key used for encoding. Figure 1: MPD Quantum Random Number Generator Micro Photon Devices S.r.l. – Italy
