The use of compact, robust, and highly scalable quantum experiments will become an increasingly important factor in the coming decades. Chip-integrated photonics offers the perfect solution for a wide range of applications in quantum technology. By miniaturizing and integrating photonic components into a chip, advantages such as improved control and manipulation of light (beam waists of a few µm) to atoms are made possible. Combined with surface traps for ions, photonic layers in the trap realize the scalability of ion-based quantum computers. Within the joint project ATIQ, we develop integrated photonics for an ion-based quantum computer with the goal to realize 40 qubits (ions). We present simulations and measurements of our integrated optical components, such as waveguides or outcouplers, chip designs, and characterization setups for linear and circular light across the UV to IR wavelength range.
