Summary

• What is new: Introduction of a real-time two-source quantum randomness extractor adapted for forward block sources, a new category of min-entropy sources.
• Why this is important: The challenge of extracting randomness in the presence of quantum side information posed by quantum adversaries.
• What the research proposes: A block-wise parallelizable, real-time extractor that can efficiently process infinitely long independent forward block sources to generate high-quality randomness.
• Results: Achieved a simulated extraction speed of 64 Gbps using raw data from a common quantum random number generator.
