    "abstract": "We discuss stochastic resonance (SR) effects in driven coupled quantum\nsystems. We construct dynamical and information theoretic measures of the\nsystem\u0027s response that exhibit a non-monotonic behaviour as a function of the\nnoise strength. We analyze the relation between lack of monotonicity in the\nresponse and the presence of quantum correlations and identify parameter\nregimes where the breakdown of a linear response can be linked to the presence\nof entanglement. We also show that a chain of coupled spin systems can exhibit\nan array-enhanced response, where the sensitivity of a single resonator is\nenhanced as a result of nearest-neighbour coupling. These results enlarge the\ndomain where SR effects exist and should be observable in arrays of\nsuperconducting qubits.",
