We describe the features of the non-equilibrium stationary states reached by a kicked linear chain made of three qubits in contact with a zero temperature dissipative environment and report the emergence of stationary entanglement between a pair of qubits of the linear chain when periodic kicks are applied simultaneously to this pair of qubits. In our scheme, the steady entanglement emerges as a result of the collective action of dissipation and kicks. We explore in this paper some of the conditions under which stationary entanglement emerges. Furthermore, the application of periodic kicks as the driven mechanism, allows us to calculate in a simple way, some of the thermodynamical properties of the non-equilibrium steady states and study their relation to the emergence of entanglement.
