Semidefinite-programming hierarchies for classically simulable state families
Mengyan Li, Yanning Jia, Fenzhuo Guo +3
Identifying whether a state family admits an irreducible quantum advantage is a fundamental task in quantum resource theory and quantum information processing. Here we study classi…
Geometric Construction of Optimal Teleportation Witnesses
Yanning Jia, Fenzhuo Guo, Mengxuan Bai +3
Not all entangled states are useful for quantum teleportation. We present a geometric method to construct optimal teleportation witnesses, which provide operational necessary and s…
Semi-device-independent certification of high-dimensional quantum channels
Mengyan Li, Yanning Jia, Fenzhuo Guo +3
Certifying high-dimensional quantum channels is essential for ensuring the reliability of quantum communication protocols. Existing certification schemes often rely on fully truste…
A General Framework for Constructing Local Hidden-state Models to Determine the Steerability
Yanning Jia, Fenzhuo Guo, Mengyan Li +2
Not all entangled states can exhibit quantum steering, and determining whether a given entangled state is steerable is a crucial problem in quantum information theory. The main cha…
Unbounded-input explicit Bell inequalities for general quantum networks
Yao Xiao, Fenzhuo Guo, Haifeng Dong +1
Quantum nonlocality in networks featuring multiple independent sources underpins large-scale quantum communication and poses fundamental challenges for its characterization. In thi…
Measuring network quantum steerability utilizing artificial neural networks
Mengyan Li, Yanning Jia, Fenzhuo Guo +3
Network quantum steering plays a pivotal role in quantum information science, enabling robust certification of quantum correlations in scenarios with asymmetric trust assumptions a…
Tight upper bound of the maximal quantum violation of Gisin's elegant Bell inequality and its application in randomness certification
Dan-Dan Hu, Meng-Yan Li, Fen-Zhuo Guo +3
The violation of a Bell inequality implies the existence of nonlocality, making device-independent randomness certification possible. This paper derives a tight upper bound for the…
Characterizing the set of quantum correlations in prepare-and-measure quantum chain-shaped networks
Yanning Jia, Fenzhuo Guo, YuKun Wang +2
We introduce a hierarchy of tests satisfied by any probability distribution that represents the quantum correlations generated in prepare-and-measure (P\&M) quantum chain-shape…
Sharing tripartite nonlocality sequentially using only projective measurements
Yiyang Xu, Hao Sun, Fenzhuo Guo +2
Bell nonlocality is a valuable resource in quantum information processing tasks. Scientists are interested in whether a single entangled state can generate a long sequence of nonlo…
