Gauge theories appear broadly in physics, ranging from the standard model of particle physics to long-wavelength descriptions topological systems condensed matter. However, with sign problems are largely inaccessible classical computations and also beyond current limitations digital quantum hardware. In this work, we develop an analog approach simulating gauge experimental setup that employs dipolar spins (molecules or Rydberg atoms). We consider molecules fixed space interacting through...
Lattice QCD is notorious for its computational expense. Modern lattice simulations require large-scale resources to handle the high number of Dirac operator inversions used construct correlation functions. Machine learning (ML) techniques that can increase, at analysis level, information inferred from functions would therefore be beneficial. We apply supervised infer two-point different target masses. Our work proposes a new method separating data into training and bias correction subsets...
A topological $\ensuremath{\theta}$-term in gauge theories, including quantum chromodynamics $3+1$ dimensions, gives rise to a sign problem that makes classical Monte Carlo simulations impractical. Quantum are not subject such problems and promising approach studying these theories the future. In near term, it is interesting study simpler models retain some of physical phenomena interest their implementation on hardware. For example, dimensionally reducing small spatial tori produces...
The decay rate of a metastable vacuum is usually calculated using semiclassical approximation to the Euclidean path integral. extension complete lattice Monte Carlo computation, however, hampered by analytic continuations that are ill-suited numerical treatment, and nonequilibrium nature state. In this paper we develop new methodology compute rates from simulations theories. To test method, consider simple quantum mechanical systems with vacua. This work can be extended field theories, which...
Suppression of diabatic transitions in quantum adiabatic evolution stands as a significant challenge for ground state preparations. Counterdiabatic driving has been proposed to compensate losses and achieve shortcut adiabaticity. However, its implementation necessitates the generation gauge potential, which requires knowledge spectral gap instantaneous Hamiltonians involves highly non-local drivings many-body systems. In this work, we consider local counterdiabatic (LCD) with approximate...

We study the promising idea of using dipolar molecular systems as analog quantum simulators for link models, which are discrete versions lattice gauge theories. In a model variables have finite number degrees freedom and values. construct effective Hamiltonian system molecules with electric dipole-dipole interactions, where we use tunable parameters to match it target describing $U(1)$ in $1+1$ dimensions.
