Does hegemony—legitimated rule by dominant power—have a role in ordering world politics of the twenty-first century? If so, what form does that hegemony take: does it lie with a leading state or with some other force? How does contemporary world hegemony operate: what tools does it use and what outcomes…

Quantum annealing belongs to a family of quantum optimization algorithms designed to solve combinatorial optimization problems using programmable quantum hardware. In this thesis, various methods are developed and tested to understand how to formulate combinatorial optimization problems for quantum…
