A minimal implementation of SU(N) pure Yang-Mills theory on digital quantum computers is presented with simplified Hamiltonians, improved infinite-mass convergence, and SU(2) embedding into R^4, benchmarked by Monte Carlo simulations.

A quantum simulation framework is developed and demonstrated for energy loss and hadronization of a heavy quark in 1+1D SU(2) lattice gauge theory on 18 qubits of IBM hardware, with results matching classical simulations.
Ultracold-atom processor samples driven thermalized Bose-Hubbard states up to 64 sites (Hilbert space 10^19), achieving sampling rates three orders of magnitude above supercomputers and extracting up to 14th-order correlations to distinguish thermalized from localized phases.
Numerical eigenstates of three particles in a circular trap reveal scarred states and towers of states explained by an unstable classical trajectory.

Quantifying Quantum Computational Advantage on a Processor of Ultracold Atoms
Ultracold-atom processor samples driven thermalized Bose-Hubbard states up to 64 sites (Hilbert space 10^19), achieving sampling rates three orders of magnitude above supercomputers and extracting up to 14th-order correlations to distinguish thermalized from localized phases.
