We present a generator producing unique and truly random bit sequences based on the measurement of the quantum uncertainty of a continuous variable vacuum state. Vacuum states have the advantage of being inherently pure states, i.e. they cannot be tempered with by an adversary and are easily detectable. Therefore, they are an ideal resource for a quantum RNG. Our RNG consists of a simple homodyne detection system.
