Harnessing Non-convex Quantum Correlations of Independent Qubits
Liang-Liang Sun, Xiang Zhou, Chengjie Zhang +3
Quantum correlations in Bell and prepare-and-measure experiments are central resources for probing nonclassicality and enabling device-based quantum information protocols. In the a…

Entanglement Detection Beyond Local Bound with Coarse Calibrated measurements
Liang-Liang Sun, Yong-Shun Song, Sixia Yu
Bell's test, initially devised to distinguish quantum theory from local hidden variable models through {violations of local bounds}, is also a common tool for detecting entanglemen…

Non-commuting Observables are Jointly Measureable under Disturbance Correction Strategy
Liang-Liang Sun, Yong-Shun Song, Zhi-Xin Chen +1
In the study of Heisenberg's error-disturbance relation, it is commonly believed that the non-unitary change of states hinders us from deducing the information encoded in original…
