Improving qubit coherence times by surface engineering
Characterization of surfaces is currently a hot topic for the fabrication of superconducting quantum processors. One way to determine surface properties is the measurement of the contact angle of a deionized water droplet on the surface of differently fabricated chips. For this purpose a measurement setup will be built within this thesis. Afterwards the images will be analyzed using a software called "ImageJ" to extract the contact angle between the chipsurface and the droplet. To compare the results from contact angle measurements to qubit performance, qubit chips will be fabricated and measured at cryogenic temperatures.
