Two-dimensional ion trap array with integrated photnics — •Dominique Zehnder — Paul Scherrer Institute, Villigen, Switzerland
One step toward scaling ion traps for quantum technologies is to deliver the laser light from within the trap chip. Photonic integration of infrared laser light was previously demonstrated in surface electrode ion traps [Mehta2019]. Our ion trapping group at PSI, in collaboration with ETHZ, is deploying the next generation of integrated photonics ion traps combining waveguides fabricated from Al2O3 for ultraviolet and Si3N4 for infrared light. In our setup we employ a 2D array of 20 trapping zones to implement key elements of the QCCD architecture [Kielpinski]. Besides applications in quantum information processing with parallel coherent control, we envision to demonstrate clock operation using multiple atomic ensembles [Borregard, Hume / Leibrandt].
