<span>Quantum simulations of QCD require digitization of the infinite-dimensional gluon field. Schemes for doing this with the minimum amount of qubits are desirable. I will present a practical digitization for
<span><span><span><span><span><span>S</span><span>U</span><span>(</span><span>3</span><span>)</span></span></span></span></span></span> gauge theories via its discrete subgroup
<span><span><span><span><span><span>S</span><span>(</span><span>1080</span><span>)</span></span></span></span></span></span> and use classical lattice calculations to explore its viability in the nonperturbative regime. Using a modified action that allows classical
simulations down to <span><span><span><span><span><span>a</span><span>—</span></span></span></span></span><span><span><span>0.08</span></span></span></span> fm, the low-lying glueball spectrum is computed with percent-level precision at multiple lattice spacings
and shown to extrapolate to the continuum limit <span><span><span><span><span><span>S</span><span>U</span><span>(</span><span>3</span></span></span></span></span></span>) results. This, perhaps surprisingly result, suggests that this digitization scheme of
the infinite SU(3) group by only 1080 finite elements is sufficient for precision quantum simulations of QCD.</span></span><u><b><span style="font-family:Calibri,Helvetica,sans-serif"><br>
