Advanced Technologies for Superconducting Qubits: Coplanar Waveguide Resonators

What it is about

You participate in a two-week lab block in which you practically learn fabrication and characterization of components for superconducting qubits (in particular coplanar waveguide resonators). At the end you will be able to micro-pattern resonators, characterize them morphologically and electrically, and analyze and interpret low-temperature RF measurement data.

What you will be able to do

• Describe the construction and operation of fundamental components of superconducting qubit technology
• Understand challenges in fabrication and performance of superconducting coplanar waveguide resonators
• Fabricate superconducting resonators using micro-patterning and etching techniques
• Characterize the morphology and structure of the resonators (AFM, profilometer, optical microscope)
• Explain methods of RF- and DC-characterization of superconductors and resonators
• Analyze and model RF measurement data from resonators
• Present results concisely in writing and orally

What the module consists of

• LaborpraktikumHands-on execution of fabrication and measurement steps under guidance; central component of the module
• Einführungen/PräsentationenTheoretical and safety-related introduction by tutors at the beginning and ongoing
• Datenanalyse und BerichtEvaluation of measurement data and creation of a scientific lab report
