Quantum self-testing is a tool that can allow us to test the honesty of quantum devices without needing to have access to any trusted quantum devices. Through classical information alone (measurement settings and outcomes, for example) we can verify that quantum devices are operating according to some specification, even if we have no information on how the devices are constructed. Self-testing can be used to test sources, measurements, and even entire quantum computations. In this talk I will go over the basics of self-testing and discuss some known self-tests and applications.
