Resolving molecular biexcited states using classical leading-order triples corrections to quantum equation-of-motion UCCSD
Zachary W. Windom, Prince Kwao, Luke Bertels +3
Excited electronic states are difficult to accurately and tractably model, particularly those exhibiting multiexcitonic character. Scalable single-reference excited state methods t…
Analysis of fourth-, fifth-, and infinite-order triple excitations in unitary coupled cluster theory
Zachary W. Windom, Daniel Claudino
In this work, we introduce a correction to the unitary coupled cluster method with single and double excitations (UCCSD) that incorporates the effects of missing triple excitations…
Toward the "platinum standard" of quantum chemistry on quantum computers: perturbative quadruple corrections in unitary coupled cluster theory
Zachary W. Windom, Luke Bertels, Daniel Claudino +1
We propose a non-iterative, post hoc correction to the unitary coupled cluster theory with single, double, and triple excitations (UCCSDT) ansatz, which considers the leading-order…
