Probing entanglement across the energy spectrum of a hard-core Bose-Hubbard lattice
Amir H. Karamlou, Ilan T. Rosen, Sarah E. Muschinske +16
Entanglement and its propagation are central to understanding a multitude of physical properties of quantum systems. Notably, within closed quantum many-body systems, entanglement…
Quantum Inspired Optimization for Industrial Scale Problems
William P. Banner, Shima Bab Hadiashar, Grzegorz Mazur +7
Model-based optimization, in concert with conventional black-box methods, can quickly solve large-scale combinatorial problems. Recently, quantum-inspired modeling schemes based on…
