  We show that a simple experimental setting of a locally pumped and lossy
array of two-level quantum systems can stabilize states with strong long-range
coherence. Indeed, by explicit analytic construction, we show there is an
extensive set of steady-state density operators, from minimally to maximally
entangled, despite this being an interacting open many-body problem. Such
nonequilibrium steady states arise from a hidden symmetry that stabilizes Bell
pairs over arbitrarily long distances, with unique experimental signatures. We
demonstrate a protocol by which one can selectively prepare these states using
dissipation. Our findings are accessible in present-day experiments.
