Ion trap fabrication at PTB — •André P. Kulosa, Alexandre Didier, Malte Brinkmann, and Tanja E. Mehlstäubler — QUEST Institute, Physikalisch-Technische Bundesanstalt, Braunschweig, Germany

Ion traps are the heart of quantum computers and simulators based on laser-cooled ions, but also a key essential of quantum clocks and precision spectroscopy. Here we report on progress and future prospects of the ion trap fabrication in the QUEST Institute at PTB. As a consequence of the quantum initiative call from the German Federal Government, the BMBF supports the transfer of quantum technology from research to industry enabling the second quantum revolution. Within the BMBF-funded opticlock project, our technology platform will be used to demonstrate a compact Yb⁺ ion optical clock replacing hydrogen masers as a future frequency reference. In a second funded project, IDEAL, we investigate integrated optics on diamond wafer chip traps enabling robust and compact interaction of laser light with the ions for the next generation of ion traps.

In the frame of its mission as governmental body to support German science and industry, PTB placed the corner stone for a Quantum Technology Competence Center (QTZ). The newly founded QTZ will focus on transfer of PTB’s expertise in quantum technology from science to application in collaboration with partners from industry and academia. For this purpose, our ion trap technology will be made accessible to external users in a new user facility providing lab infrastructure.
