摘要
In a recent paper [S.-L. Chen et al., Quantum 5, 552 (2021)], the authors proposed a framework for robustly self-testing steerable quantum assemblages. In this work, we apply their method to the scenario of self-testing two-qubit entangled quantum states. Our bounds on the fidelity with the reference states are compared with other methods.
