  Pure quantum states can be stabilized in open quantum systems subject to
external driving forces and dissipation by environmental modes. We show that
driven dissipative (DD) Majorana devices offer key advantages for stabilizing
degenerate state manifolds (`dark spaces') and for manipulating states in dark
spaces, both with respect to native (non-DD) Majorana devices and to DD
platforms with topologically trivial building blocks. For two tunnel-coupled
Majorana boxes, using otherwise only standard hardware elements (e.g., a noisy
electromagnetic environment and quantum dots with driven tunnel links), we
propose a dark qubit encoding. We anticipate exceptionally high fault tolerance
levels due to a conspiracy of DD-based autonomous error correction and
topology.
