• Abstract: 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.

  Self-testing is a promising approach to certifying quantum states or measurements. We show how to self-test any four- (three-) outcome extremal positive operator-valued measure using a linear witness. One of our constructions achieves self-testing of any number of states with the help of as many projective measurements.

  We develop a general self-testing procedure for multipartite generalized GHZ-state measurements. The key step is self-testing all measurement eigenstates for a general N-qubit multipartite GHZ-state measurement. It turns out that the existing result for three-qubit GHZ-state measurement is recovered as a special case.
