Flexibility of the factorized form of the unitary coupled cluster Ansatz

Jia Chen et al.

Summary: The factorized form of unitary coupled cluster Ansatz provides flexibility to choose different approximation methods, ranging from conventional configuration interaction to conventional unitary coupled cluster, as well as efficient approximations in between. Through variational minimization of the energy, simplified factorized unitary coupled cluster approximations can achieve high accuracy, even if they do not accurately approximate the Trotter product formula.

Quantum-Inspired Algorithm for the Factorized Form of Unitary Coupled Cluster Theory

Jia Chen et al.

Summary: The factorized form of UCC shows similar accuracy to conventional CC for weakly correlated molecules and significantly outperforms CI for strongly correlated molecules, making it an accurate, efficient, and reliable electronic structure method in both weakly and strongly correlated regions. This classical algorithm allows for robust benchmarking of anticipated quantum computing results and application of coupled-cluster techniques to more strongly correlated molecules.
