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…
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…
State preparation in quantum algorithms for fragment-based quantum chemistry
Ruhee D'Cunha, Matthew Otten, Matthew R. Hermes +2
State preparation for quantum algorithms is crucial for achieving high accuracy in quantum chemistry and competing with classical algorithms. The localized active space unitary cou…
Challenges in the use of quantum computing hardware-efficient Ansatze in electronic structure theory
Ruhee D'Cunha, T. Daniel Crawford, Mario Motta +1
Advances in quantum computation for electronic structure, and particularly heuristic quantum algorithms, create an ongoing need to characterize the performance and limitations of t…
