A quantum correlation is said to be a self-test if it has a unique quantum model. Self-testing has become an important concept in quantum information, where it is used in a range of applications from practical to theoretical. This includes the recent MIP*=RE theorem of Ji, Natarajan, Wright, Vidick, and Yuen, which provides a counterexample to the Connes embedding problem. In this talk, I’ll give an overview of self-testing, how it’s used in the MIP*=RE theorem, and it’s connections with flexible stability of group relations.
