Certification and estimation of quantum randomness — •Stefano Pironio — Laboratoire d'Information Quantique, Université libre de Bruxelles (ULB), Belgium

Contrarily to classical physics, quantum physics allows for the generation of numbers which are random even to a potential adversary that could have a complete knowledge of the randomness generating device. Furthermore, the generated entropy can be certified and estimated even if the devices are not entirely trusted thanks to the concept of self-testing. In this talk, I review and explain the theoretical framework used to assess the entropy generated by such self-testing quantum devices.
