Extended Ion Strings

The Extended Ion Strings project focusses on advancing ion trap quantum information processing, with a particular emphasis on trapping long ion strings, controlling multiple ion species and individual addressing single ions. Its modular and versatile setup supports various quantum computing and precision measurement applications.

Key technical features of the setup include:

• A waveguide array for precise and low-crosstalk single-ion addressing within ion strings.
• A low-latency camera and FPGA for real-time ion detection and feedback as for instance required for mid-circuit quantum error correction.
• A cryogenic system, essential to achieve the required vacuum stability to trap long ion strings.

Given its technical capabilities, the various past and future research directions span from quantum information processing to precision measurements and include:

• rapping of very long linear ion strings with over 100 ions (see figure 1).
• Developing a new quantum readout scheme using focused beams from the individual addressing system.
• Precision measurements of calcium isotopes to investigate physics beyond the Standard Model.
• Quantum error correction schemes with multi-isotope operations.
