Ions trapped on chips are one of the most promising approaches for quantum computers. The approach offers the advantage of high fidelity, long coherence time and scalability. In addition, the ion physics and trap chip technology are well understood. The key component for the scalability of this quantum computers are integrated optical devices, such as waveguides to transport light or grating outcouplers to emit *m beams to the ions. In the joint project ATIQ, this approach is being pursued with the aim of realising a quantum computer with 40 qubits (ions). We present simulations of integrated optical components, their applications on chips and our characterization setups.
