3D-printed ion traps for scalable quantum information processing

A 3D-printed trap fabricated at LLNL has recently demonstrated single ion coherent manipulations, confirming compatibility of materials with ion-trap quantum hardware [1]. In spite of impressive performance metrics, the trap design is not scalable. In this poster, we describe our effort towards setting up an ion trapping experiment to explore scalable 3D-printed ion

traps. Millimeter-scale traps have been printed at LLNL with their axis parallel to the trap substrate. In conjunction with dc control-electrodes on the surface, these traps will enable ion transport operations for the QCCD architecture. In the near term, we will benchmark the performance of the printed ion traps with a trapped ⁴⁰Ca⁺ ion.
