HybridAlpha: An Efficient Approach for Privacy-Preserving Federated Learning
Runhua Xu, Nathalie Baracaldo, Yi Zhou +2
Federated learning has emerged as a promising approach for collaborative and privacy-preserving learning. Participants in a federated learning process cooperatively train a model b…
Quantum Orbital-Optimized Unitary Coupled Cluster Methods in the Strongly Correlated Regime: Can Quantum Algorithms Outperform their Classical Equivalents?
Igor O. Sokolov, Panagiotis Kl. Barkoutsos, Pauline J. Ollitrault +4
The Coupled Cluster (CC) method is used to compute the electronic correlation energy in atoms and molecules and often leads to highly accurate results. However, due to its single-r…
Ground-state properties of the hydrogen chain: insulator-to-metal transition, dimerization, and magnetic phases
Mario Motta, Claudio Genovese, Fengjie Ma +14
Accurate and predictive computations of the quantum-mechanical behavior of many interacting electrons in realistic atomic environments are critical for the theoretical design of ma…
Electric-Field Control of the Interlayer Exchange Coupling for Magnetization Switching
Shehrin Sayed, Cheng-Hsiang Hsu, Niklas Roschewsky +2
We propose an electric-field-controlled mechanism for magnetization switching assisted solely by the interlayer-exchange coupling (IEC) between the fixed and the free magnets, whic…
Electronic structure of bulk manganese oxide and nickel oxide from coupled cluster theory
Yang Gao, Qiming Sun, Jason M. Yu +5
We describe the ground- and excited-state electronic structure of bulk MnO and NiO, two prototypical correlated electron materials, using coupled cluster theory with single and dou…
Direct comparison of many-body methods for realistic electronic Hamiltonians
Kiel T. Williams, Yuan Yao, Jia Li +22
A large collaboration carefully benchmarks 20 first principles many-body electronic structure methods on a test set of 7 transition metal atoms, and their ions and monoxides. Good…
