Cluster-State Witnesses of Finite-Speed Hidden Influences
Weikang Li, Mengyao Hu, Dong-Ling Deng +1
Bell experiments rule out local common-cause explanations of quantum correlations, yet they do not exclude hidden influences that travel faster than light while still having a fini…
Graph Theoretic Approach to Quantum Nonstabilizerness
Yingjian Liu, Albert Gasull, Mengyao Hu +3
Detecting nonstabilizerness requires full tomography and an optimization over exponentially many stabilizer states. A limited Pauli measurement set promises resource-efficient magi…
Optimizing and Certifying Multipartite Permutationally Invariant Bell Inequalities
Jin-Fu Chen, Mengyao Hu, Jordi Tura
Multipartite Bell nonlocality provides a device-independent probe of many-body quantum correlations, but its characterization is limited by the rapid growth of the underlying class…
Many-body -local ground states as probes for unitary quantum metrology
Majid Hassani, Mengyao Hu, Guillem Müller-Rigat +2
Multipartite quantum states saturating the Heisenberg limit of sensitivity typically require full-body correlators to be prepared. On the other hand, experimentally practical Hamil…
Optimizing quantum violation for multipartite facet Bell inequalities
Jin-Fu Chen, Mengyao Hu, Jordi Tura
Nonlocality shapes quantum correlations, revealed through the violation of Bell inequalities. The intersection of all valid Bell inequalities is the so-called local polytope. In mu…
Spin Group Symmetry Criteria for Odd-parity Magnets
Xun-Jiang Luo, Jin-Xin Hu, Meng-Li Hu +1
Odd-parity magnets (OPMs) have recently emerged as a new magnetic class, but their general symmetry criteria remain elusive. In this Letter, we establish these criteria through a c…
Improved Nonlocality Certification via Bouncing between Bell Operators and Inequalities
Weikang Li, Mengyao Hu, Ke Wang +25
Bell nonlocality is an intrinsic feature of quantum mechanics, which can be certified via the violation of Bell inequalities. It is therefore a fundamental question to certify Bell…
Characterizing Translation-Invariant Bell Inequalities using Tropical Algebra and Graph Polytopes
Mengyao Hu, Eloïc Vallée, Tim Seynnaeve +3
Nonlocality is one of the key features of quantum physics, which is revealed through the violation of a Bell inequality. In large multipartite systems, nonlocality characterization…
Probing many-body Bell correlation depth with superconducting qubits
Ke Wang, Weikang Li, Shibo Xu +32
Quantum nonlocality describes a stronger form of quantum correlation than that of entanglement. It refutes Einstein's belief of local realism and is among the most distinctive and…
Effects of Topological Boundary Conditions on Bell Nonlocality
Patrick Emonts, Mengyao Hu, Albert Aloy +1
Bell nonlocality is the resource that enables device-independent quantum information processing tasks. It is revealed through the violation of so-called Bell inequalities, indicati…
