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…
Self-Testing Positive Operator-Valued Measurements and Certifying Randomness
Wenjie Wang, Mengyan Li, Fenzhuo Guo +2
In the device-independent scenario, positive operator-valued measurements (POVMs) can certify more randomness than projective measurements. This paper self-tests a three-outcome ex…
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…
