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…
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…
Witnessing nonlocality in quantum network of continuous-variable systems by generalized quasiprobability functions
Taotao Yan, Jinchuan Hou, Xiaofei Qi +1
Gaussian measurements can not be used to witness nonlocality in Gaussian states as well as the network nonlocality in networks of continuous-variable (CV) systems. Thus special non…
