Device-independent self-testing allows user to identify the measured quantum states and the measurements made in a device using the observed statistics. Such verification scheme only requires assuming the validity of quantum theory and no-signalling. As such, no assumptions are required about the inner-workings of the device. Hence, self-testing allows laymen to test the serviceability of a quantum device without needing its blueprint. This talk will be primarily focused on the self-testing of bipartite entangled pure states [Nat. Comms. 8, 15485 (2017)]. Also, I will be touching on the recent study of the geometry of the quantum set [In preparation].
