Ultra-fast real-time quantum random number generator with correlated measurement outcomes and rigorous security certification

Understand

Quantum random number generators (QRNGs) promise perfectly unpredictable random numbers.

• However, the security certification of the random numbers in form of a stochastic model often introduces assumptions that are either hardly justified or indeed unnecessary.
• Two important examples are the restriction of an adversary to the classical regime as well as negligible correlations between consecutive measurement outcomes.
• Additionally, non-rigorous system characterization opens a security loophole.
