- Abstract summary: We show a new approach to the generation of custom entangled many-body states through reservoir engineering.
We outline an algorithm where, beginning with a desired set of squeezing correlations, one uses the symmetry to constrain the Hamiltonian.
We demonstrate how to use this process to stabilize two unique pure states with non-local correlations that could be useful for quantum information applications.

- Abstract: We demonstrate a new approach to the generation of custom entangled many-body
states through reservoir engineering, using the symmetry properties of bosonic
lattice systems coupled to a local squeezed reservoir. We outline an algorithm
where, beginning with a desired set of squeezing correlations, one uses the
symmetry to constrain the Hamiltonian and find a lattice configuration which
stabilizes a pure steady state realizing these correlations. We demonstrate how
to use this process to stabilize two unique pure states with non-local
correlations that could be useful for quantum information applications. First,
we show how drive a square lattice into a product state of entangled
quadruplets of sites. Second, using a bisected system, we generate a steady
state where local measurements in one half of the lattice herald a pure
delocalized state in the second half.

We provide a systematic framework for constructing generic models of nonequilibrium quantum dynamics with a target stationary (mixed) state.
We focus on Gibbs states of stabilizer Hamiltonians, identifying local Lindbladians compatible therewith by constraining the rates of dissipative and unitary processes.
Our methods also reveal new models of quantum dynamics: for example, we provide a "measurement-induced phase transition" where measurable two-point functions exhibit critical (power-law) scaling with distance at a critical ratio of the transverse field and rate of measurement and feedback.

The main idea is to work out how a previously proposed sequence of two stabilization steps can be applied instead in appropriate (probabilistic) superposition.
We examine alternatives to synchronize the superposition using local couplings only, thanks to a chain of "clock" ancillas or to additional levels on the data subsystems.

We show that the steady state of the system undergoes a localization entanglement phase transition by tuning $p$ which remains stable in the presence of coherent hopping.

Remarkably, the incoherent operation classes all admit the same second order expansions.
