Robust semi-device-independent certification of all pure bipartite maximally entangled states via quantum steering

The idea of self-testing is to render guarantees concerning the inner workings a device based on measurement statistics. It one most formidable quantum certification and benchmarking schemes. Recently it was shown by Coladangelo et. al. (Nat Commun 8, 15485 (2017)) that all pure bipartite entangled states can be self tested in independent scenario employing subspace methods introduced Yang (Phys. Rev. A 87, 050102(R)). Here, we have adapted their method show any state certified semi-device through Quantum Steering. Analogous tilted CHSH inequality, use steering inequality called Tilted Steering Inequality for certifying two-qubit state. Further, this certify two-dimensional sub-spaces qudit observing structure set assemblages obtained trusted side after measurements are made un-trusted side. As feature via steering, notion Assemblage robust provide robustness bounds result case maximally local dimension.
