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…
Optimising entanglement distribution policies under classical communication constraints assisted by reinforcement learning
Jan Li, Tim Coopmans, Patrick Emonts +3
Quantum repeaters play a crucial role in the effective distribution of entanglement over long distances. The nearest-future type of quantum repeater requires two operations: entang…
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…
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…
Multiple-basis representation of quantum states
Adrián Pérez-Salinas, Patrick Emonts, Jordi Tura +1
Classical simulation of quantum physics is a central approach to investigating physical phenomena. Quantum computers enhance computational capabilities beyond those of classical re…
Spectral Gap Optimization for Enhanced Adiabatic State Preparation
Kshiti Sneh Rai, Jin-Fu Chen, Patrick Emonts +1
The preparation of non-trivial states is crucial to the study of quantum many-body physics. Such states can be prepared with adiabatic quantum algorithms, which are restricted by t…
