Description
It is highly nontrivial to verify the correctness of large-scale quantum computations beyond the reach of classical computers. Focusing on the fact that the axial anomaly in gauge theories is exact to all orders in perturbation theory, we propose the axial anomaly as a benchmark for quantum simulations of lattice gauge theories. We simulate anomalous axial-charge production on the Quantinuum quantum computer Reimei and reproduce the anomaly coefficient within statistical uncertainties, even without error mitigation. Our results demonstrate that the axial anomaly can serve as a verification test for current and future quantum computations.
