Excited-State Downfolding Using Ground-State Formalisms

Nicholas P. Bauman

Downfolding coupled cluster (CC) techniques are powerful tools for reducing the dimensionality of many-body quantum problems. This work investigates how ground-state downfolding fo…

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…

Quantum flow algorithms for simulating many-body systems on quantum computers

Karol Kowalski, Nicholas P. Bauman

We conducted quantum simulations of strongly correlated systems using the quantum flow (QFlow) approach, which enables sampling large sub-spaces of the Hilbert space through couple…
