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…
Exploring the boundary of quantum network states from inside out
Xiang Zhou, Zhen-Peng Xu, Liang-Liang Sun +2
Quantum networks with bipartite resources and shared randomness present the simplest infrastructure for implementing a future quantum internet. Here, we shall investigate which kin…
Bounding the amount of entanglement from witness operators
Liang-Liang Sun, Xiang Zhou, Armin Tavakoli +2
We present an approach to estimate the operational distinguishability between an entangled state and any separable state directly from measuring an entanglement witness. We show th…
Lower-bounding entanglement with nonlocality in a general Bell's scenario
Liang-Liang Sun, Xiang Zhou, Zhen-Peng Xu +1
Understanding the quantitative relation between entanglement and Bell nonlocality is a long-standing open problem of fundamental and practical interest. Here, we tackle this proble…
From entanglement to discord: a perspective based on partial transposition
Sun Liang-Liang, Zhou Xiang, Yu Sixia
Here, we show that partial transposition, which is initially introduced to study entanglement, can also inspire many results on quantum discord including: (I) a discord criterion o…
Certifying randomness in quantum state collapse
Liang-Liang Sun, Xingjian Zhang, Xiang Zhou +4
The unpredictable process of state collapse caused by quantum measurements makes the generation of quantum randomness possible. In this paper, we explore the quantitive connection…
Uncertainty-disturbance relations and applications
Liang-Liang Sun, Kishor Bharti, Xiang Zhou +3
Uncertainty and intrinsic measurement disturbance, two fundamental concepts in quantum measurement, have conventionally been viewed as distinct and studied separately. In this work…
No Disturbance Without Uncertainty as a Physical Principle
Liang-Liang Sun, Xiang Zhou, Sixia Yu
Finding physical principles lying behind quantum mechanics is essential to understand various quantum features, e.g., the quantum correlations, in a theory-independent manner. Here…
