Optimizing Resonator Packaging to Identify Packaging Bottlenecks for Large-Scale Quantum Processors

Purpose and goal

The overall goal of this project is to address the question "How does packaging affect the performance of superconducting quantum bits?". This is done by testing resonators that have significantly higher Q-values and are thus more sensitive to disturbances from the environment.

Expected effects and result

Develop a validated guideline of the packaging aspects affecting resonator performance to identify best practices for packaging large-scale quantum processors.

Planned approach and implementation

In the project we will investigate different aspects of the impact of packaging. First through simulations, and then by validating these using resonators. This gives us an understanding of the factors that limit the resonator´s performance.
