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…
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…
Nearly-frustration-free ground state preparation
Matthew Thibodeau, Bryan K. Clark
Solving for quantum ground states is important for understanding the properties of quantum many-body systems, and quantum computers are potentially well-suited for solving for quan…
Simulating Quantum Mechanics with a -term and an 't Hooft Anomaly on a Synthetic Dimension
Jiayu Shen, Di Luo, Chenxi Huang +4
A topological -term in gauge theories, including quantum chromodynamics in 3+1 dimensions, gives rise to a sign problem that makes classical Monte Carlo simulations impractical.…
