  In recent times, device-independent certification of quantum states has been
one of the intensively studied areas in quantum information. However, all such
schemes utilise projective measurements which are practically difficult to
generate. In this work, we consider the one-sided device-independent (1SDI)
scenario, and propose a self-testing scheme for the two-qubit maximally
entangled state using non-projective measurements, in particular, three
three-outcome extremal POVM's. We also analyse the robustness of our scheme
against white noise.
