  We 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.
