A major issue in nanoscience concerns the influence of the environment on quantum networks The present analysis considers the simplest model of current between two electronic reservoirs via a quantum dot The noisy environment is modeled by a single nearby impurity which jumps randomly between two states so called telegraph noise and affects the electronic states on the dot Earlier works found the effect of telegraph noise on the charge current due the voltage difference between the reservoirs Surprisingly we find 1 that there is a heat current from the noisy environment into the quantum network even in the absence of a voltage drop The heat currents from the noisy environment into the two reservoirs may differ from each other thus creating a temperature gradient between the reservoirs 1 O Entin Wohlman D Chowdhury A Aharony and S Dattagupta arXiv:1710 05626 Accepted in Phys Rev B
