    "abstract": "There is growing interest to investigate states of matter with topological\norder, which support excitations in the form of anyons, and which underly\ntopological quantum computing. Examples of such systems include lattice spin\nmodels in two dimensions. Here we show that relevant Hamiltonians can be\nsystematically engineered with polar molecules stored in optical lattices,\nwhere the spin is represented by a single electron outside a closed shell of a\nheteronuclear molecule in its rotational ground state. Combining microwave\nexcitation with the dipole-dipole interactions and spin-rotation couplings\nallows us to build a complete toolbox for effective two-spin interactions with\ndesignable range and spatial anisotropy, and with coupling strengths\nsignificantly larger than relevant decoherence rates. As an illustration we\ndiscuss two models: a 2D square lattice with an energy gap providing for\nprotected quantum memory, and another on stacked triangular lattices leading to\ntopological quantum computing.",
