We present the status of a cryogenic (4K) experimental set-up for quantum computing with radio frequency (RF)-controlled trapped ions. It incorporates a novel micro-structured planar Paul trap with integrated micromagnets and we report on the characterization of the first trap generation to be used in this set-up. Also, progress in developing laser cooling techniques for mixed Yb⁺-Ba⁺ crystals is reported.
