      abstract     = {For quantum computers, there are two theoretical models
                      which are nowadays considered to be the most important: the
                      gate-based quantum computer and the quantum
                      annealer.Gate-based quantum computers are based on
                      computational gates just like classical computers are, but
                      have potentially more computational power due to the algebra
                      behind quantum theory. A quantum annealer works
                      fundamentally different: First the system is prepared in a
                      known ground state of an initial Hamiltonian, then this
                      Hamiltonian is adiabatically transformed into the final
                      Hamiltonian whose ground state corresponds to the solution
                      of a given problem, usually taken from the class of
                      optimization problems.Quantum annealing works well in theory
                      if the qubits can be described by two-level systems.
                      However, in real devices qubits are not based on a perfect
                      two-level system, but on a two-dimensional subspace of a
                      larger system. This makes approximations in analytic
                      calculations unavoidable.With a simulation utilizing the
                      Suzuki-Trotter product-formula approach for solving the
                      time-dependent Schrödinger equation, the time-evolution of
                      the full state of such a device based on superconducting
                      flux qubits is investigated.},
