The concept of resonating valence bond state lies at the heart of fundamental many-body quantum physical phenomena, such as high temperature superconductivity and topological quantum computation. In this talk we will present our results on direct experimental evidence of a valence bond quantum resonance with ultracold bosonic atoms. The atoms are manipulated using a superlattice structure, creating a three-dimensional array of independent four-site plaquettes. Furthermore, we will show how resonating valence bond states with s- and d-wave symmetry can be created and characterized. These two states constitute a minimum basis of a topologically protected qubit.
