    ENGLISH ABSTRACT: Quantum annealing is a form of quantum computing that incorporates algorithms and hardware design to solve optimization problems. Evidence suggests that quantum an- nealing can be superior to classical solvers for certain optimizations. However, quantum computers including quantum annealing devices are more susceptible to errors than clas- sical computers hence the inclusion of some form of protection against errors in quantum annealing is important to ensure scalability. In this thesis, we address the issue of control errors in the accuracy of solutions obtained via a quantum annealer through optimiza- tion of the control fields v ia t he K rotov m ethod. C ontrol fi elds op timized in th is way for a problem with known solutions can be used to mitigate control errors of a similar problem.
