In lattice QCD spacetime is represented not as continuous but as a crystalline lattice, vertices connected by lines. Quarks may reside only on vertices and gluons can only travel along lines. While this is understood to be a fiction, the hope is that as the spacing between vertices is reduced to zero, or to the Planck length, the theory will yield meaningful results.
This technique is only applicable in the domain of low density and high temperature; at higher densities, the region alas of greatest interest, the fermion sign problem renders the results useless. Lattice QCD predicts that confined quarks will become released to quark-gluon plasma around energies of 170 MeV. Lattice QCD's limitation to low density does not allow investigation of the color flavor locked states (CFL) at higher densities.
Lattice QCD has already made contact with experiments at various fields with good results. A particular important tool of the theory showing the confinement of the underlying fields is the Wilson loop variable, described in a separate article.
