Multireference Embedding and Fragmentation Methods for Classical and Quantum Computers: from Model Systems to Realistic Applications
Shreya Verma, Abhishek Mitra, Qiaohong Wang +8
One of the primary challenges in quantum chemistry is the accurate modeling of strong electron correlation. While multireference methods effectively capture such correlation, their…
Non-unitary Variational Quantum Eigensolver with the Localized Active Space Method and Cost Mitigation
Qiaohong Wang, Ruhee D'Cunha, Abhishek Mitra +4
Accurately describing strongly correlated systems with affordable quantum resources remains a central challenge for quantum chemistry applications on near and intermediate-term qua…
Quantum-centric Supercomputing for Materials Science: A Perspective on Challenges and Future Directions
Yuri Alexeev, Maximilian Amsler, Paul Baity +124
Computational models are an essential tool for the design, characterization, and discovery of novel materials. Hard computational tasks in materials science stretch the limits of e…
The Localized Active Space Method with Unitary Selective Coupled Cluster
Abhishek Mitra, Ruhee D'Cunha, Qiaohong Wang +5
We introduce a hybrid quantum-classical algorithm, the localized active space unitary selective coupled cluster singles and doubles (LAS-USCCSD) method. Derived from the localized…
