Quantum theory, being inherently probabilistic, leads to the generation of randomness. If the quantum system and measuring apparatus that produce the randomness are however treated as a ‘black box’ about which the inner workings are not known, then it becomes impossible to certify that it is a genuine source of randomness. This problem can be overcome by using entangled particles distributed between numerous parties, and relies on quantum nonlocality. In this talk I will present a number of results about randomness certification in quantum theory based upon different variants of quantum nonlocality.
