Quantum simulations of excited states with active-space downfolded Hamiltonians
Nicholas P. Bauman, Guang Hao Low, Karol Kowalski
Many-body techniques based on the double unitary coupled cluster ansatz (DUCC) can be used to downfold electronic Hamiltonians into low-dimensional active spaces. It can be shown t…
Well-conditioned multiproduct Hamiltonian simulation
Guang Hao Low, Vadym Kliuchnikov, Nathan Wiebe
Product formula approximations of the time-evolution operator on quantum computers are of great interest due to their simplicity, and good scaling with system size by exploiting co…
Q# and NWChem: Tools for Scalable Quantum Chemistry on Quantum Computers
Guang Hao Low, Nicholas P. Bauman, Christopher E. Granade +9
Fault-tolerant quantum computation promises to solve outstanding problems in quantum chemistry within the next decade. Realizing this promise requires scalable tools that allow use…
Downfolding of many-body Hamiltonians using active-space models: extension of the sub-system embedding sub-algebras approach to unitary coupled cluster formalisms
Nicholas P. Bauman, Eric J. Bylaska, Sriram Krishnamoorthy +3
In this paper we outline the extension of recently introduced the sub-system embedding sub-algebras coupled cluster (SES-CC) formalism to the unitary CC formalism. In analogy to th…
