      abstract     = {Charge stability diagrams provide information about the
                      electron occupation of double quantum dots. They are used
                      during the tuning process of double quantum dots, necessary
                      to enable their operation as quantum bits. Simulated charge
                      stability diagrams are required for testing and developing
                      automated tuning algorithms. They are well suited for that
                      because they can be generated fast and the ground truth
                      occupation is known for a simulated data point. In contrast,
                      the measuring of experimental datasets takes a long time and
                      the ground truth is unknown. This thesis deals with the
                      simulation of distortions in simulated charge stability
                      diagrams. For the simulation of the undisturbed occupation
                      data, the capacitive model [1] and the Hubbard model [2] are
                      presented. However, both models are not suited for the
                      simulation of the honeycomb structures visible in available
                      experimental charge stability diagrams. Another approach,
                      currently developed by Fabian Hader from the ZEA-2, is used
                      to overcome this problem.To simulate realistic charge
                      stability diagrams, the sensor response including
                      distortions has to be added to the clean occupation data.
                      Five types of distortions are identified: cross-coupling
                      between sensor and double dot plunger gates, white noise,
                      pink noise,random telegraph noise, and dot jumps. For a
                      realistic simulation of these, procedures to determine
                      parameter ranges from the experimental charge stability
                      diagrams are developed and applied. Then, the generated
                      simulated dataset is evaluated visually and by different
                      metrics. To improve the quality of the simulated dataset,
                      the initial parameters are adjusted, and the simulation
                      model itself is refined. Finally, the optimized simulated
                      dataset is evaluated with the same metrics, and the results
                      are discussed.},
