Closed-Form Expressions for Unitaries of Spin-Adapted Fermionic Operators
Ilias Magoulas, Francesco A. Evangelista
One of the open challenges in quantum computing simulations of problems of chemical interest is the proper enforcement of spin symmetry. Efficient quantum circuits implementing uni…
Fermionic Mean-Field Theory as a Tool for Studying Spin Hamiltonians
Thomas M. Henderson, Brent Harrison, Ilias Magoulas +5
The Jordan--Wigner transformation permits one to convert spin operators into spinless fermion ones, or vice versa. In some cases, it transforms an interacting spin Hamiltonia…
CNOT-Efficient Circuits for Arbitrary Rank Many-Body Fermionic and Qubit Excitations
Ilias Magoulas, Francesco A. Evangelista
Efficient quantum circuits are necessary for realizing quantum algorithms on noisy intermediate-scale quantum devices. Fermionic excitations entering unitary coupled-cluster (UCC)…
Controlling quantum interference between virtual and dipole two-photon optical excitation pathways using phase-shaped laser pulses
Jurick Lahiri, Stephen H. Yuwono, Ilias Magoulas +5
Two-photon excitation (TPE) proceeds via a "virtual" pathway, which depends on the accessibility of one or more intermediate states, and, in the case of non-centrosymmetric molecul…
Is Externally Corrected Coupled Cluster Always Better than the Underlying Truncated Configuration Interaction?
Ilias Magoulas, Karthik Gururangan, Piotr Piecuch +2
The short answer to the question in the title is 'no'. We identify classes of truncated configuration interaction (CI) wave functions for which the externally corrected coupled-clu…
Isoenergetic Two-Photon Excitation Enhances Solvent-to-Solute Excited-State Proton Transfer
Jurick Lahiri, Mehdi Moemeni, Jessica Kline +9
Two-photon excitation is an attractive means for controlling chemistry in both space and time. Isoenergetic one- and two-photon excitations (OPE and TPE) in non-centrosymmetric mol…
