TETRIS-ADAPT-VQE: An adaptive algorithm that yields shallower, denser circuit ansätze
Panagiotis G. Anastasiou, Yanzhu Chen, Nicholas J. Mayhall +2
Adaptive quantum variational algorithms are particularly promising for simulating strongly correlated systems on near-term quantum hardware, but they are not yet viable due, in lar…
Symmetry breaking slows convergence of the ADAPT Variational Quantum Eigensolver
Luke W. Bertels, Harper R. Grimsley, Sophia E. Economou +2
Because quantum simulation of molecular systems is expected to provide the strongest advantage over classical computing methods for systems exhibiting strong electron correlation,…
New Local Explorations of the Unitary Coupled Cluster Energy Landscape
Harper R. Grimsley, Nicholas J. Mayhall
The recent quantum information boom has effected a resurgence of interest in unitary coupled cluster (UCC) theory. Our group's interest in local energy landscapes of unitary ansätz…
Coupled electron pair-type approximations for tensor product state wavefunctions
Vibin Abraham, Nicholas J. Mayhall
Size extensivity, defined as the correct scaling of energy with system size, is a desirable property for any many-body method. Traditional CI methods are not size extensive hence t…
Scaling adaptive quantum simulation algorithms via operator pool tiling
John S. Van Dyke, Karunya Shirali, George S. Barron +3
Adaptive variational quantum simulation algorithms use information from the quantum computer to dynamically create optimal trial wavefunctions for a given problem Hamiltonian. A ke…
Quantum self-consistent equation-of-motion method for computing molecular excitation energies, ionization potentials, and electron affinities on a quantum computer
Ayush Asthana, Ashutosh Kumar, Vibin Abraham +8
Near-term quantum computers are expected to facilitate material and chemical research through accurate molecular simulations. Several developments have already shown that accurate…
