Sur l’identification des états produits par une source quantique maximalement décorrélée
We define a maximally uncorrelated quantum source as an ensemble of quantum states, each taken in a different base from a set of mutually unbiased basis and such that the number of states equals the dimension of the space they live in. We explore upper bounds on the probability of distinguishing such states using numerical and analytical techniques. We also propose a novel cryptographic protocol for a non interactive proof of knowledge in which such a source is used as the main technical tool for the security proof.
