Perspectives for experiments with trapped anti-matter ions and fast transport and separation operations in segmented Paul traps

Ions confined in a Paul trap arrange in crystals and allow for a unique control and analysis. Building on the developments of segmented traps as architecture for a future quantum computer, we aim for experiments with a single trapped anti-matter ion of positively charged hydrogen (p-/2e+). The QUANTUM group is participating in the GBAR collaboration for a free-fall experiment with ultra-cold anti-matter atoms. After outlining the experimental scheme taken by GBAR, I focus on the required techniques including capturing anti-H ions, fast ion transport, steering of single-ion beams at a spatial resolution of 8 nm, separation operations, as well as sympathetic cooling to the quantum mechanical ground state of vibration. I estimate how accurately the gravitation of anti-H may be determined and discuss further applications for trapped anti-H ions.
