Experimental certification of multipartite Bell correlations using only few-body symmetric correlations
Jiacheng Sun, Mengyao Hu, Paweł Cieśliński +9
Certifying Bell correlations in increasingly larger multipartite quantum systems is challenging because conventional Bell inequalities rely on many-body correlations, which become…
Quantum states supported by matroids
Xiaowei Huang, Fei Shi, Lijun Zhang +1
In this work, we establish a structural correspondence between quantum states and matroid theory. This connection demonstrates that key properties of quantum states, including enta…
Optimal qudit overlapping tomography and optimal measurement order
Shuowei Ma, Qianfan Wang, Lvzhou Li +1
Quantum state tomography is essential for characterizing quantum systems, but it becomes infeasible for large systems due to exponential resource scaling. Overlapping tomography ad…
Experimental Multipartite Entanglement Detection With Minimal-Size Correlations
Dian Wu, Fei Shi, Jia-Cheng Sun +5
Multiparticle entanglement is a valuable resource for quantum technologies, including measurement based quantum computing, quantum secret sharing, and a variety of quantum sensing…
Approximate k-uniform states: definition, construction and applications
Kaiyi Guo, Fei Shi, You Zhou +1
-Uniform states are fundamental to quantum information and computing, with applications in multipartite entanglement and quantum error-correcting codes (QECCs). Prior work has p…
Detecting entanglement and nonlocality with minimum observable length
Zhuo Chen, Fei Shi, Qi Zhao
Quantum entanglement and nonlocality are foundational to quantum technologies, driving quantum computation, communication, and cryptography innovations. To benchmark the capabiliti…
