Editing Randomness amplification (8 devices) (section)

Randomness amplification is a protocol for [[Quantum Random Number Generator]] which takes a string from a weak source of randomness - one which contains correlations and may be at least somewhat predictable by an adversary - and converts it to a (potentially shorter) string which is (close to) uniformly random and private from any adversaries. The protocol of [https://www.nature.com/articles/ncomms11345 Brandao et al] allows for eight untrusted devices to be used in a noise-tolerant setting to amplify an arbitrarily weak [https://wiki.veriqloud.fr/index.php?title=Glossary Santha-Vazirani (SV) source].

Classically, it is only possible to extract uniform, private randomness by combining multiple weak sources together. This protocol enables the extraction of such randomness from only a single weak source - useful in any situation where only some randomness has been provided but absolute security is required.
