-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…
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…
Gaussian unsteerable channels and computable quantifications of Gaussian steering
Taotao Yan, Jie Guo, Jinchuan Hou +2
The current quantum resource theory for Gaussian steering for continuous-variable systems is flawed and incomplete. Its primary shortcoming stems from an inadequate comprehension o…
