Dissipative continuation for ground-state preparation at chemical transition states
Thomas W. Watts, Soumya Sarkar, Daniel Collins +4
Simulating chemical reactions exhibits a pronounced unevenness in computational difficulty: while equilibrium reactant and product geometries are often tractable, transition-state…
Physically-Motivated Guiding States for Local Hamiltonians
Gabriel Waite, Karl Lin, Samuel J Elman +1
We study the computational complexity of the Guided Local Hamiltonian problem: given a local Hamiltonian together with a classical description of a guiding state that has non-n…
The Complexity of Local Stoquastic Hamiltonians on 2D Lattices
Gabriel Waite, Michael J. Bremner
We show the 2-Local Stoquastic Hamiltonian problem on a 2D square qubit lattice is StoqMA-complete. We achieve this by extending the spatially sparse circuit construction of Olivei…
Prospects for Quantum Computation in Propellant Design: Assessing the Stability of Cyclic Ozone in Nanoscale Confinement
Thomas W. Watts, Matthew Otten, Jason T. Necaise +14
Cyclic ozone additives have the potential to markedly increase the specific impulse of rocket fuel. This would translate to greater efficiency and reduced costs for space lift by g…
Quantum computing for corrosion-resistant materials and anti-corrosive coatings design
Nam Nguyen, Thomas W. Watts, Benjamin Link +14
Corrosion is a pervasive issue that impacts the structural integrity and performance of materials across various industries, imposing a significant economic impact globally. In fie…
