We discuss the canonical formulation of the Z(3) Potts model and its relation to heavy-dense QCD at fixed baryon number. By taking into account the local quark occupation numbers we construct a cluster algorithm which completely eliminates the fermion sign problem. In addition, the cluster formulation allows the construction of improved estimators for various observables such as the baryon chemical potential, or the quark-antiquark, quark-quark and antiquark-antiquark potentials which show the screening behaviour as expected at finite baryon density.
