Abstract in another language

We show how to generate and control the correlations in a set of two distant quantum emitters coupled to a one-dimensional dissipative plasmonic waveguide. An external laser field enhances the dimer’s steady-state correlations and allows an active control (switching on/off) of nonclassical correlations. The plasmon-assisted dipolar-interacting qubits exhibit persistent correlations, which in turn can be decoupled and made to evolve independently from each other. The setup enables long-distance (∼1µm) qubit control that works for both resonant and detuned emitters. For suitable emitter initialization, we also show that the quantum correlation is always greater than the classical one.
