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…
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…
-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…
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…
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…
