Advancements in Ultra-High Vacuum Technology for Trapped Ion Quantum Computing — •Helin Özel, Tabea Stroinski, Julian Harald Wiener, Felix Stopp, Björn Lekitsch, and Ferdinand Schmidt-Kaler — Johannes Gutenberg University, Mainz, Germany

We present experimental results on advancements in ultra-high vacuum (UHV) technology to support the development of next-generation quantum processor systems for continuous and stable operation at room-temperature. Our research focuses on improving UHV technology by applying innovative coating techniques. We optimize the pumping speed and achieve improved pressure levels alongside with reduced degassing rates, which are essential for maintaining the stability of quantum systems. Additional improvements address optical alignment and in-vacuum designs to support long-term operation. For preservation of qubit coherence we use three layers of Mu-metal shielding against magnetic noise, while a Halbach magnet configuration is employed to generate a stable magnetic quantization field. These advancements will enhance the reliability and operation quality of the trapped ion processor.
