We study driven-dissipative dynamics of a network of spin-1/2 systems coupled to chiral 1D bosonic waveguides [1,2]. By chiral coupling we mean an asymmetric coupling of the spin decay to the left and right propagating guided modes. Remarkably, this non-equilibrium dynamics has steady states in form of quantum dimers, or entangled spin-clusters, which form as pure dark states of the dissipative dynamics. We discuss possible photonic realizations with atoms coupled to nanofibers, or a phononic version with mixtures of quantum gases involving spin-orbit coupling. We conclude with a brief overview of recent proposlas to realize models of frustrated quantum magnetism with Rydberg atoms in optical lattices [3].
