We present quantum logic inspired manipulation and detection schemes for a CPT test experiment based on a g-factor comparison between single trapped protons and antiprotons. The basic idea is to cool, detect and manipulate single trapped (anti-)protons through their interaction with a co-trapped and laser-cooled atomic ion following the proposal by Heinzen and Wineland . We discuss ion trap geometries and spin state transfer schemes as well as laser systems and optical systems for manipulating and detecting the atomic ion.
