Geometric View of Iterative Fixed-Node Dynamics
Pranav Kairon, Bryan K. Clark
The sign-structure of a quantum many-body ground state is a central quantity in fixed-node approaches to mitigating the Fermion sign problem. For continuum electronic-structure Ham…
Analysis of Many-body Localization Landscapes and Fock Space Morphology via Persistent Homology
Gregory A. Hamilton, Bryan K. Clark
We analyze functionals that characterize the distribution of eigenstates in Fock space through a tool derived from algebraic topology: persistent homology. Drawing on recent genera…
Quantifying Unitary Flow Efficiency and Entanglement for Many-Body Localization
Gregory A. Hamilton, Bryan K. Clark
We probe the bulk geometry of the Wegner Wilson Flow (WWF) in the context of many-body localization, by addressing efficiency and bulk entanglement growth measures through approxim…
Learning ground states of quantum Hamiltonians with graph networks
Dmitrii Kochkov, Tobias Pfaff, Alvaro Sanchez-Gonzalez +2
Solving for the lowest energy eigenstate of the many-body Schrodinger equation is a cornerstone problem that hinders understanding of a variety of quantum phenomena. The difficulty…
Classical Shadows for Quantum Process Tomography on Near-term Quantum Computers
Ryan Levy, Di Luo, Bryan K. Clark
Quantum process tomography is a powerful tool for understanding quantum channels and characterizing properties of quantum devices. Inspired by recent advances using classical shado…
Quantum Circuits For Two-Dimensional Isometric Tensor Networks
Lucas Slattery, Bryan K. Clark
The variational quantum eigensolver (VQE) combines classical and quantum resources in order simulate classically intractable quantum states. Amongst other variables, successful VQE…
