SiQT 2

Scalable Integrated Ion Traps for QT

Ion traps are a key technology for future quantum systems – from quantum computers to highly precise optical atomic clocks. In particular, 3D ion traps offer excellent properties for stable and precise measurements. However, their production has so far been complex, expensive and difficult to scale.

The QVLS-iLabs project SiQT-2 is working to make this technology more compact, robust and suitable for industrial manufacturing. In the current project phase, the degree of integration of the ion trap is being significantly increased and a design is being developed that enables precise and potentially automated assembly. The goal is cost-efficient manufacturing based on suitable materials and scalable production processes.

In addition, key functions are being integrated directly into the system: compact photon detectors for reading out the ion states, photonic structures for guiding light, as well as integrated electronics for controlling the trap. This creates a highly integrated demonstrator that paves the way for portable optical atomic clocks and other metrological applications.
