This paper gives a survey of the field of magnetic topological insulators, with a focus on their coherent manipulation for technological purposes. As a reminder, a magnetic topological insulator is a topological insulator whose topological phase is not induced by an external magnetic field. Instead, the phase is induced by specialized spin-orbit coupling terms within the material. Many of the proposals for applications of topological phases of matter come from magnetic topological insulators, because they don't require a strong external magnetic field. However, these materials are still exotic and we have yet to master their manipulation. Other good surveys of the field exist, including
