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…
TRAM: A Transverse Relaxation Time-Aware Qubit Mapping Algorithm for NISQ Devices
Yifei Huang, Pascal Jahan Elahi, Ugo Varetto +3
Noisy intermediate-scale quantum (NISQ) devices impose dual challenges on quantum circuit execution: limited qubit connectivity requires extensive SWAP-gate routing, while time-dep…
-Entanglement Measure for Multipartite Systems without Convex-Roof Extensions and its Evaluation
Jie Guo, Shuyuan Yang, Jinchuan Hou +2
Multipartite entanglement underpins quantum technologies but its study is limited by the lack of universal measures, unified frameworks, and the intractability of convex-roof exten…
Multipartite correlation measures and framework for multipartite quantum resources theory
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
In recent years, it has been recognized that properties of multipartite physical systems, such as genuine multipartite entanglement, can be considered as important resources for qu…
