Abstract
A quantum random number generator (QRNG) based on the quantum nature of vacuum fluctuations allows one to obtain random bit sequences that can be used in applications that require a high degree of randomness. In that type of quantum random generation system, optical beam splitters with two inputs and two outputs are normally used. A comparison of Y-splitter and spatial beam splitters shows that for two types of optical splitters, the quantum mathematical description of output signals is identical. This allows the use of fiber Y-splitters in practical QRNG schemes. The possibility of generating true random bits was demonstrated experimentally by using quantum random number generator based on homodyne detection.
