Symmetry-driven correlation patterns in one-dimensional periodic fermionic systems: closed-form expressions and exact selection rules for correlation functions, entanglement entropies and mutual information
Celestino Angeli
We present an analytical study of the spatial structure of correlations in periodic fermionic systems at the single Slater determinant level, focusing on the cyclic case. Exploitin…
Quantum-Information Measure of Electron Localization
Stefano Pittalis, Filippo Troiani, Celestino Angeli +2
Understanding electron localization in molecules and materials plays a central role in electronic structure theory, and will increase in importance with the rise of data-driven app…
Genuine multipartite entanglement from many-electron systems
Filippo Troiani, Celestino Angeli, Andrea Secchi +1
We demonstrate that, contrary to common wisdom, genuine multipartite entanglement (GME) can be abundantly generated from simple non-correlated many-electron states. We show that th…
Quantum Information reveals that orbital-wise correlation is essentially classical in Natural Orbitals
Davide Materia, Leonardo Ratini, Celestino Angeli +1
The intersection of Quantum Chemistry and Quantum Computing has led to significant advancements in understanding the potential of using quantum devices for the efficient calculatio…
Quantum Information Driven Ansatz (QIDA): shallow-depth empirical quantum circuits from Quantum Chemistry
Davide Materia, Leonardo Ratini, Celestino Angeli +1
Hardware-efficient empirical variational ansätze for Variational Quantum Eigensolver simulations of Quantum Chemistry suffer from the lack of a direct connection to classical Quant…
