Device-independent Randomness Extraction for Arbitrarily Weak Min-entropy Source

  title={Device-independent Randomness Extraction for Arbitrarily Weak Min-entropy Source},
  author={Jan Bouda and Marcin Pawlowski and Matej Pivoluska and Martin Plesch},
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… CONTINUE READING
