Experimental implementation of a quantum random number generator based on vacuum fluctuation is presented in this paper. A Y-splitter is used in optical setup of the quantum random number generator. The generation of random numbers in real time with a speed of 300 Mb/s is demonstrated. The conditional minimum entropy is used to estimate the randomness. A cryptographic hashing function is used for post-processing. The resulting sequence has passed DieHard and NIST statistical tests successfully.

Keywords: quantum random number generation, homodyne detection, vacuum fluctuation.
