Abstract
Ion traps are one approach to represent Qubits in future quantum computer architectures. Nevertheless, progress has to be made to scale ion trap setups for multiple ions and qubit scaling. Next to the ion trap architecture itself the manipulation of the ion’s state and their readout by means of a laser and fluorescence detection optics are key architectural building blocks. A setup dedicated to the optical addressing of each individual ion in the trap will be described, consisting of micro-optics for diffraction limited focusing of the laser beam onto the ion and a miniaturized actuation mechanism for the micron scale movement of the focus with the ion, where the electrical feedback signal stems from the detection unit. The setup’s design with an initial layout for up to 10 ions in parallel can further be scaled towards ca. 50 ions in parallel at least. Publisher’s Note: The manuscript PDF, originally published on 5 March 2021, was withdrawn on 12 March 2021 per author request.
