Is it possible to check a quantum computer's work? A quantum computation leaves behind no transcript, and for problems outside nondeterministic polynomial time (NP), it is not immediately clear whether we can verify that a quantum computation has been one correctly. Interactive proofs and self-testing offer a means of doing so. In this talk I will discuss how to use self-testing for graph states and measurement based quantum computation to construct interactive proofs for any language in bounded error quantum polynomial time (BQP).
