- Abstract summary: This work reports on setup, characterisation and data processing of a true quantum random number generator.
As a randomness source a pure quantum vacuum state of light is used, which is amplified by a laser beam.
The system is able to produce true and unique random numbers at a rate of 25 Gbit/s and thus outperforms previous implementations considerably.

- Abstract: This work reports on setup, characterisation and data processing of a true
quantum random number generator. As a randomness source a pure quantum vacuum
state of light is used, which is amplified by a laser beam. Performance and
behaviour of the system as well as parasitic errors are investigated. For an
optimized exploitation of the data they are Fourier-transformed and processed
further as frequency amplitudes. The extractable entropy in that data is
calculated to allow for elimination of non-random signal contributions by
hashing. The system is able to produce true and unique random numbers at a rate
of 25 Gbit/s and thus outperforms previous implementations considerably.

This work analyzes evolutions in the extractable amount of randomness with increasing the Hilbert space dimension.
We investigate the generic case of time-bin encoding scheme, define various input (state preparation) and outcome (measurement) subspaces.
We demonstrate that this approach can boost the system entropy, resulting in more extractable randomness.

We propose two novel quantum-proof randomness extractors for reverse block sources that realize real-time block-wise extraction.
Our designs achieve a significantly higher extraction speed and a longer output data length with the same seed length.
Applying our extractors to the raw data generated by a widely used quantum random number generator, we achieve a simulated extraction speed as high as $300$ Gbps.

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.
