We present our quantum engineering approach to generate ultracold samples of polar molecules in the regime of quantum degeneracy.  Such samples are ideal for quantum simulation purposes with many-body spin systems and for probing novel phases and phase transitions in view of the long-range dipole-dipole interactions between the molecules.  Our choice of molecule is the RbCs molecule, which is a boson, and we have started a project on fermionic KCs.

The cruical step in producing low-entropy samples of ground-state RbCs molecules is to efficiently form Rb-Cs atom pairs as precursors to molecule formation in the presence of a lattice potential.  The atom pairs are created by mixing a Cs Mott insulator with a superfluid Rb sample.  We give an outlook on our goal to produce a molecular quantum simulator.
