In this work we investigate the limits to the possibility to reveal the existence of weak microwave signals through Josephson junctions. Even if the Josephson element is capable to reveal the electromagnetic field, thermal noise is to be quantified by means of signal theory, as a confounding factor that limits the detection. We show how the decision problem can be embedded in the frame of signal detection. As a consequence, the optimization of the detection probability and the minimization of the false alarm probability give a guide to select the Josephson junction parameters that best suit the purpose.

Abstract

In this work we investigate the limits to the possibility to reveal the existence of weak microwave signals through Josephson junctions. Even if the Josephson element is capable to reveal the electromagnetic field, thermal noise is to be quantified by means of signal theory, as a confounding factor that limits the detection. We show how the decision problem can be embedded in the frame of signal detection. As a consequence, the optimization of the detection probability and the minimization of the false alarm probability give a guide to select the Josephson junction parameters that best suit the purpose.
