Device-independent Randomness Extraction for Arbitrarily Weak Min-entropy Source
Bouda, Jan
Pawlowski, Marcin
Pivoluska, Matej
Plesch, Martin
In this paper we design a protocol to extract random bits with an
arbitrarily low bias from a single arbitrarily weak min-entropy block source in a device independent setting. The protocol employs Mermin devices that exhibit super-classical correlations. Number of devices used scales polynomially in the length of the block n, containing entropy of at least two bits. Our protocol is robust, it can tolerate devices that malfunction with a probability dropping polynomially in n at the cost of constant increase of the number of devices used.
