The Kitaev honeycomb model is a system allowing for experimentally realizable quantum computation with
topological protection of quantum information. Practical implementation of quantum information processing
typically relies on adiabatic, i.e., slow dynamics. Here we show that the restriction to adiabatic dynamics can be
overcome with optimal control theory, enabled by an extension of the fermionization of the Kitaev honeycomb
model to the time-dependent case. Moreover, we present a quantum control method that is applicable to large
lattice models due to subexponential scaling.
