(BSc) Optimizing Electromagnetic Coupling Interfaces in Superconducting Resonator Systems

This project explores one of the important components of quantum computing, aiming to tailor the interface between the quantum and classical worlds. The research focuses on a thorough understanding of electromagnetic coupling and superconducting resonators in a coplanar waveguide configuration. Starting from standard coupling structures, this work seeks to narrow the gap between theoretical simulations and real measurements, ultimately advancing the optimization of electromagnetic coupling interfaces in superconducting quantum computation.

Task Description

Coplanar waveguide resonators are key components for reading out qubit information in quantum computing. To obtain quantum information rapidly, the resonator must be strongly coupled to a transmission line. However, standard coupling structures suffer from large feature sizes and discrepancies between simulation and measurement. This project aims to identify a coupling structure that occupies less space and can be accurately predicted using simulation software.

Required Skills

To participate in this project, you must have a solid theoretical understanding of electromagnetic fields and transmission line theory. Basic experience with COMSOL or Sonnet simulation software is highly recommended. You should be able to work effectively in a small team and collaborate with students engaged in diverse projects using the same setup. Since all of our measurements are code-based, experience with Python is required.
