  Implementations of solid state quantum optics provide us with devices where
qubits are placed at fixed positions in photonic or plasmonic one dimensional
waveguides. We show that solely by controlling the position of the qubits and
with the help of a coherent driving, collective spontaneous decay may be
engineered to yield an entangled mesoscopic steady-state. Our scheme relies on
the realization of pure superradiant Dicke models by a destructive interference
that cancels dipole-dipole interactions in one-dimension.
