- Abstract: Randomness is a very important resource for cryptography, algorithms, and
scientific simulations. Since all classical processes are considered to be
intrinsically deterministic, we must build quantum random number generators
which utilize quantum processes to generate true randomness. Quantum random
number generators have been realized in different quantum systems, including
quantum optical systems, and trapped ions. Here we present a proof-of-concept
random number generator based on a nuclear spin system for the first time. The
state preparation and measurements are performed with high-fidelity operations
in our system. The entropy of randomness in the experimental data is quantified
by two dimension witness certification protocols, which require no detailed
models to describe the experimental devices but only some general assumptions,
such as the limited dimensionality and the independence of the experimental
devices.

We use a toy fiber optic based setup to generate binary series, and evaluate their level of randomness according to Ville principle.
Series are tested with a battery of standard statistical indicators, Hurst, Kolmogorov complexity, minimum entropy, Takensarity dimension of embedding, and Augmented Dickey Fuller and Kwiatkowski Phillips Schmidt Shin to check station exponent.
The level of randomness of series obtained by applying Toeplitz extractor to rejected series is found to be indistinguishable from the level of non-rejected raw ones.

Quantum random number generators generally require well modeled and calibrated light sources, such as a laser, to generate randomness.
With uncharacterized light sources, such as sunlight or an uncharacterized laser, genuine randomness is practically hard to be quantified or extracted owing to its unknown or complicated structure.
We exploit a recently proposed source-independent randomness generation protocol and experimentally realize the modified scheme with an uncharacterized laser and a sunlight source.
