The creation of hybrid systems consisting of Rydberg atoms and coplanar superconducting resonators has been proposed to enable efficient state transfer between solid state systems and ultracold atoms. Due to the large dipole moment of Rydberg atoms, the coupling strength to the cavity is expected to be much larger than for ground state atoms. At the same time, Rydberg states are strongly affected by any detrimental fields, such as the electric field of adsorbates on the chipsurface, which lead to spatially inhomogeneous energy shifts. We aim to transfer population between neighbouring Rydberg states using the microwave field of a driven coplanar waveguide resonator on a superconducting atom chip. The state transfer in the presence of adsorbate fields is detected via selective field ionisation. Ultimately, this method may aid in the observation of Rabi oscillations between neighbouring Rydberg states.
