Trapped-ion quantum computing is one of the most promising platforms in quantum information processing, where qubits are realized as energy levels of single ionized atoms. The preparation, manipulation and read out of the states are driven by laser light, requiring the implementation of optical access into the ion trap.
We present the fabrication route of an ion trap with multiple metal layers on a structured glass substrate. In cooperation with Johanneum Research, the glass substrate is structured by employing a selective laser etching technique, such that it allows additional optical access through the backside of the trap and thus higher flexibility in the laser setup. At Infineon Technologies in Villach, the implementation of the fabrication flow for multi-metal deposition is realized. Future steps include the prototype testing and development of the high optical access laser setup, contributing to making scalable ion traps a reality.
