A posteriori corrections to the Iterative Qubit Coupled Cluster method to minimize the use of quantum resources in large-scale calculations
Ilya G. Ryabinkin, Artur F. Izmaylov, Scott N. Genin
The iterative qubit coupled cluster (iQCC) method is a systematic variational approach to solve the electronic structure problem on universal quantum computers. It is able to use a…
Unitary transformation of the electronic Hamiltonian with an exact quadratic truncation of the Baker-Campbell-Hausdorff expansion
Robert A. Lang, Ilya G. Ryabinkin, Artur F. Izmaylov
Application of current and near-term quantum hardware to the electronic structure problem is highly limited by qubit counts, coherence times, and gate fidelities. To address these…
Iterative Qubit Coupled Cluster approach with efficient screening of generators
Ilya G. Ryabinkin, Robert A. Lang, Scott N. Genin +1
An iterative version of the qubit coupled cluster (QCC) method [I.G. Ryabinkin et al., J. Chem. Theory Comput. 14, 6317 (2019)] is proposed. The new method seeks to find ground ele…
Quantum chemistry on quantum annealers
Scott N. Genin, Ilya G. Ryabinkin, Artur F. Izmaylov
Quantum chemistry calculations for small molecules on quantum hardware have been demonstrated to date only on universal-gate quantum computers, not quantum annealers. The latter de…
Symmetry adaptation in quantum chemistry calculations on a quantum computer
Ilya G. Ryabinkin, Scott N. Genin
Quantum chemistry calculations on a quantum computer frequently suffer from symmetry breaking: the situation when a state of assumed spin and number of electrons is contaminated wi…
Revising measurement process in the variational quantum eigensolver: Is it possible to reduce the number of separately measured operators?
Artur F. Izmaylov, Tzu-Ching Yen, Ilya G. Ryabinkin
Current implementations of the Variational Quantum Eigensolver (VQE) technique for solving the electronic structure problem involve splitting the system qubit Hamiltonian into part…
