Protons on the move
The BASE international research collaboration, in which Heinrich Heine University Düsseldorf (HHU) is strongly involved, has successfully relocated protons outside of an antimatter laboratory for the first time with the help of an autonomous, open Penning trap. This breakthrough marks a significant step toward transporting antiprotons produced at the European Organisation for Nuclear Research (CERN) to high-precision laboratories such as BASE-HHU, which operate independently of the research facility. As the researchers now explain in the scientific journal Nature, extremely precise measurements to compare matter and antimatter are only possible far from accelerator facilities.

Nondestructive quantum state control of a single molecular hydrogen Ion
Using the ALPHATRAP Penning trap at MPIK, physicists demonstrated nondestructive control and readout of internal quantum states of a molecular hydrogen ion. The new method provides essential prerequisites for future high-precision tests of the CPT symmetry.
- Single molecular hydrogen ions are for more than a month in the ALPHATRAP Penning trap.
- Internal quantum states of the molecular hydrogen ion are controlled and detected nondestructively.
- The experiment demonstrates a proof-of-concept for future measurements of antimatter molecular hydrogen ions.
