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…
Quantum network-entanglement measures
Zhen-Peng Xu, Julio I. de Vicente, Liang-Liang Sun +1
Quantum networks are of high interest nowadays and a quantum internet has been long envisioned. Network-entanglement adapts the notion of entanglement to the network scenario and n…
