Verifying full quantum network nonlocality in arbitrary configurations by nonlinear Bell-like inequalities
Shuyuan Yang, Jinchuan Hou, Kan He +1
Full quantum network nonlocality (FQNN) describes a scenario where all sources in a network are nonlocal. Existing criteria of FQNN can only be verified in star networks by violati…
Ascent and descent of bounded linear operators
Xiaofei Qi, Xiaoshuo Feng, Bing Xu +1
The paper investigates ascent and descent of bounded linear operators on Banach spaces, providing characterizations for rank‑one and rank‑two operators and describing maps that pre…
Imaginarity Resource Theory of Gaussian Quantum Channels
Ting Zhang, Jinchuan Hou, Xiaofei Qi
Complex numbers play an indispensable role in quantum mechanics and quantum information, as validated by both theoretical analysis and experimental verification. Since quantum info…
Mutually-commuting von Neumann algebra models of quantum networks and violation of Bell-type inequalities
Shuyuan Yang, Jinchuan Hou, Kan He
Employing mutually-commuting von Neumann algebras to represent the algebra of observables on quantum systems provides a framework for studying quantum information theory in systems…
Violation of Bell-type Inequalities on Mutually-commuting von Neumann Algebra Models of Entanglement Swapping Networks
Bingke Zheng, Shuyuan Yang, Jinchuan Hou +1
Violation of Bell inequalities in bipartite systems represented by mutually-commuting von Neumann algebras has pioneered the study of vacuum entanglement in algebraic quantum field…
Negativity Percolation in Continuous-Variable Quantum Networks
Yaqi Zhao, Kan He, Yongtao Zhang +4
Quantum networks (QNs) have been predominantly driven by discrete-variable (DV) architectures. Yet, optical platforms naturally generate Gaussian states--the common states of conti…
