Quantum-random number generators (QRNG) are key componenents for quantum-key distribution systems. In addition, compared to conventional true-random number generators, they offer advantages in generation rate and modelling of the entropy source.
We present an experimental QRNG based on balanced homodyne detection of the quantum-optical vacuum state. This QRNG is designed for operations under the restrictive requirements of a 3U CubeSat.
The optical part of the QRNG is monolithically integrated on an Indium-Phosphide photonic-integrated circuit and is placed on a 10x10 cm2 printed-circuit board accomodating necessary electronics. We show first conclusive results obtained with this system and discuss its operation in space.
