The entropy accumulation theorem [11] states that the smooth minentropy of an n-partite system A = (A1, . . . , An) is lower-bounded by the sum of the von Neumann entropies of suitably chosen conditional states up to corrections that are sublinear in n. This theorem is particularly suited to proving the security of quantum cryptographic protocols, and in particular so-called device-independent protocols for randomness expansion and key distribution, where the devices can be built and… CONTINUE READING
