Abstract
Quantum state discrimination depicts the general progress of extracting classical information from quantum systems. We show that quantum state discrimination can be realized in a measurement device-independent scenario using tools of self-testing results. That is, the states can be discriminated credibly with the untrusted experiment devices by the correspondence between quantum correlations and states. In detail, we show that two states that are not conjugate with each other can be discriminated without additional trusted input states, and the discrimination of others require a kind of trusted inputs. Further we show the guessing probability analysis of this protocol for minimum error discrimination, which is acceptable based on numerical results.
