Title: Heat it up and watch! A strategy to protect distant entanglement.

Abstract
In composed quantum systems, the presence of local dissipative channels causes loss of coherence and entanglement at a rate that grows with the temperature of the reservoirs. Here, we invert the role of dissipation by showing how the creation of artificial temperature, together with the ability to monitor the subsystems locally, can be used to preserve the entanglement of the system. The scheme, being based only on local measurements and operations, opens the possibility to preserve entanglement over long distances and also between different nodes of a network composed of multiple qubits.
