Abstract
Random numbers which are unpredictable and definitely unknown by anyone before they are generated are now used in a large number of real-world applications ranging from authentication, gaming, many online activities to simulations and optimizations. The development of a trusted randomness source is thus a necessity. In this work we present a simple design of a certifiable quantum random number generation and its. In particular we show how real-time low-latency randomness can be generated from measurements on time-bin photonic states every 0.12s. We generate a block of 2^13 random bits certifiable against the most powerful quantum adversary with its error bounded by 2^-64. Further our device is suitable for continuous operation giving it a potential application as a quantum randomness beacon.
