  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. However, here we show that if temperature is
artificially added to the system, entanglement decay can be significantly
slowed down or even suppressed conditioned on suitable local monitoring of the
reservoirs. We propose a scheme to implement the joint reservoir monitoring
applicable in different experimental setups like trapped ions, circuit and
cavity QED or quantum dots coupled to nanowires and we analyze its general
robustness against detection inefficiencies and non-zero temperature of the
natural reservoir.
