Exact noise characterization of entanglement distribution in star networks
Kenneth Goodenough, Xiaonan Chen, Patrick Emonts
Multipartite entanglement forms the core of many networking applications. In the near-term future, it is expected that multipartite distribution will be achieved first through star…
A Hierarchy of Spectral Gap Certificates for Frustration-Free Spin Systems
Kshiti Sneh Rai, Ilya Kull, Patrick Emonts +3
Estimating spectral gaps of quantum many-body Hamiltonians is a highly challenging computational task, even under assumptions of locality and translation-invariance. Yet, the quest…
Tailoring Bell inequalities to the qudit toric code and self testing
Eloïc Vallée, Owidiusz Makuta, Patrick Emonts +2
Bell nonlocality provides a robust scalable route to the efficient certification of quantum states. Here, we introduce a general framework for constructing Bell inequalities tailor…
Boosting thermalization of classical and quantum many-body systems
Jin-Fu Chen, Kshiti Sneh Rai, Patrick Emonts +5
Understanding and optimizing the relaxation dynamics of many-body systems is essential both for foundational studies in quantum thermodynamics and for applications such as quantum…
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…
Learning Pole Structures of Hadronic States using Predictive Uncertainty Estimation
Felix Frohnert, Denny Lane B. Sombillo, Evert van Nieuwenburg +1
Matching theoretical predictions to experimental data remains a central challenge in hadron spectroscopy. In particular, the identification of new hadronic states is difficult, as…
