Random numbers play an essential role in many applications, such as quantum key distribution, simulations and classical cryptography. In this work, we discuss the photonic and electronic integration of a quantum random number generator (QRNG) based on measurements on the quantum mechanical vacuum state. The experimental setup is based on an InP photonic integrated circuit, containing all required components on a 4 x 4.6 mm chip. This could give access to a portable and reliable QRNG potentially achieving rates in the GHz regime.
