Impact of high-rank excitations on accuracy of the unitary coupled cluster downfolding formalism
Karol Kowalski, Bo Peng, Nicholas P. Bauman
In this paper, we evaluate the accuracy of the Hermitian form of the downfolding procedure utilizing the double unitary coupled cluster Ansatz (DUCC) on the H6 and H8 benchmark sys…

Coupled cluster downfolding techniques: a review of existing applications in classical and quantum computing for chemical systems
Nicholas P. Bauman, Bo Peng, Karol Kowalski
In this manuscript, we provide an overview of the recent developments of the coupled cluster (CC) downfolding methods, where the ground-state problem of a quantum system is represe…
