Abstract
The generation of entanglement is studied in a minimal model consisting of two independent Gaussian parties embedded in a common heat bath and subject to local control signals. Neither the reservoir alone nor the external driving can induce quantum non-locality but only the cooperative impact of both in non-equilibrium. It is shown that this corresponds to a dynamical symmetry breaking between the modes. By applying optimal control protocols substantial entanglement is generated even for single-site control and at higher temperatures and is preserved after the control is switched off.
