Exploring topological signatures of quantum Fisher information scaling in graph states
Majid Hassani, Patrick Emonts, Jordi Tura
Graph states are a versatile resource for quantum metrology, and their quantum Fisher information (QFI) has a closed-form expression in terms of the underlying graph: it counts pai…
Two-Sided Bounds on Ground State Properties in Lattice Gauge Theories
Eloïc Vallée, Ariel Kelman, Julius Mildenberger +2
Gauge theories describe fundamental interactions in the standard model of particle physics and build effective theories in condensed matter physics. Being notoriously hard to simul…
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…
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…
Random Projections for Multi-Copy Quantum Algorithms
Xiaoyu Liu, Jordi Tura, Johannes Knörzer
Estimating nonlinear properties of quantum states is a central task in quantum information science. Multivariate traces, , and nonlinear observables su…
