N2 - Surface-electrode ion traps with integrated microwave conductors for near-field quantum control are a promissing approach for scaleable quantum computers. The goal of the QVLS-Q1 Project is to realize the first scalable 50-qubit quantum computer based on surface-electrode ion traps. Designing a multi-layer ion trap with surface-electrodes for electromagntic near-field operations comes with high demands on the design of the electrical components, such as impedance matching of the surface electrodes to the microwave and radio frequency sources. The near field had to be designed considering the necessary conditions to trap 9Be+- Ions in a multi layer trap. This process will be presented in this talk, emphasising on the constraints of the electrically small chip size compared to the length of the applied electromagnetic waves. In electromagnetic full-wave simulations we can show that a properly desinged electrode combined with an efficient impedance matching accounts for a significant decrease of electrical losses. The design of the meander-like microwave guide will be discussed including the simulation methods and approaches.
