Self-Testing of Quantum States Using Symmetric Local Hidden State Model

We introduce a symmetric local hidden state $(slhs)$ model in scenario, where two spacially separated parties receive quantum states from an unknown source. derive inequality based on the model. A completely new form of nonlocality emerges resource theoretic point view. The singles out larger set correlated higher dimensional scenarios $(d> 2 $ X $2)$ than what is predicted by existing $lhs$ model, opening front for experimentalists to test accuracy prediction. propose experiment show experimental violation qubit scenario and perform IBM computer. However, method adopted two-qubit does not naturally generalize leaves verification claim open. also that maximal can be used self-test Bell measurement bases, leading complete device-independence.
