%X The quantum approximate optimisation algorithm (or QAOA) is a variational algorithm. The algorithm consists of two parts. A quantum step which evaluates a cost function and a classical step which performs the optimisation. The hope is that the classical optimisation step can mitigate errors which appear in state-of-the-art quantum processors.We investigate this idea by simulating the time evolution of superconducting quantum processors with two and three qubits. The model which generates the dynamics of the system is a lumped-element circuit Hamiltonian model. We find that in this model the classical optimisation step can mitigate some of the gate errors which are caused by imperfect two-qubit gates.
