Abstract
The robustness of quantum electrical current magnification in the face of thermodynamical decoherence is studied. Thermodynamical calculations for the specific heat, internal energy and electrical current suggest that magnification is decimated by temperature. The range of validity of the phenomenon is at order of the equivalent spectral band. With respect to the Milburn theory of decoherence, electrical current magnification is robust. Moreover, magnification phenomenon is widely exhibited in a large variety of quantum circuits and a wide variety of experimental setups can be envisaged.
