Randomness amplification (8 devices): Difference between revisions

[https://www.nature.com/articles/ncomms11345 Brandão et. al.] also provide a protocol that achieves randomness amplification using only four devices, however, the randomness extractor required to produce multiple bits is only defined implicitly (i.e. we can prove that it exists but have not yet been able to construct it). A randomness extractor does exist that is able to produce a single private bit.
