SiQT

Scalable Integrated Ion Traps for Quantum Technology

One of the future scenarios being worked on in the Cluster4Future QVLS-iLabs is an ion-based quantum computer. For this, however, the ions (or qubits) not only have to be trapped, but also controlled and moved. 3D ion traps are well suited for this. They offer the best performance characteristics for scientific, quantum metrology and quantum sensing applications. However, 3D ion traps have some disadvantages for commercial production, such as the high costs of the materials used, the use of special manufacturing techniques and the difficult assembly.

The QVLS-iLabs project SiQT addresses these disadvantages. The goal of SiQT is the cost-effective industrial production of chip ion traps without manual alignment. To achieve this goal, production processes are to be expanded, among other things, to use less expensive materials (replacement of gold electrodes with gold-plated copper) and photodetectors and switching electronics based on the industrially established CMOS technology are to be developed and integrated.

This project has been successfully completed.
