  We study controlled generation and measurement of superfluid d-wave
resonating valence bond (RVB) states of fermionic atoms in 2D optical lattices.
Starting from loading spatial and spin patterns of atoms in optical
superlattices as pure quantum states from a Fermi gas, we adiabatically
transform this state to an RVB state by change of the lattice parameters.
Results of exact time-dependent numerical studies for ladders systems are
presented, suggesting generation of RVB states on timescale smaller than
typical experimental decoherence times.
