ΠερίληψηWe analyze the possible quantum correlations between two coupled dimer systems in the presence of independent losses and driven by a fluctuating field. For the case of the interaction being of a Heisenberg exchange type, we first analytically show the possibility for robust stationary entanglement for realistic values of the dissipation rates and then analyze its robustness as a function of the noise to signal ratio of the pump. We find that for a common fluctuating driving field, a stochastic resonance effect appears as function of the ratio between field strength and noise strength. The effect disappears in the case of uncorrelated or separate pumps. Our result is general and could be applied to different quantum systems ranging from electron spins in solid state, to ions trap technologies and cold atom set ups.en
