Device-independent randomness extraction for arbitrarily weak min-entropy source
Seminar Room 1, Newton Institute
In this work we show how to use the GHZ Mermin inequality based devices to extract one bit of randomness from an (n,2) min-entropy source for arbitrary n. The extracted bit can be arbitrarily close to the uniform bit. The number of devices we use scales polynomially with n, what allows to tolerate (reasonably) imperfect GHZ devices.
