  We study the dissipative preparation of many-body entangled Gaussian states
in bosonic lattice models which could be relevant for quantum technology
applications. We assume minimal resources, represented by systems described by
particle-conserving quadratic Hamiltonians, with a single localized squeezed
reservoir. We show that in this way it is possible to prepare, in the steady
state, the wide class of pure states which can be generated by applying a
generic passive Gaussian transformation on a set of equally squeezed modes.
This includes non-trivial multipartite entangled states such as cluster states
suitable for measurement-based quantum computation.
