Recent years have witnessed substantial progress in using interactions between Rydberg excited atoms for quantum gates and entanglement generation. Nevertheless there remain several outstanding challenges that must be overcome to achieve scalable quantum computation. These include gate fidelity, atom loss, and quantum nondemolition state measurements without crosstalk to nearby qubits. After reviewing the current state of the art we will present some new ideas for simple solutions using complex atoms.
