Abstract
A Josephson parametric device is presented, which includes an input port, an output port, and a signal path between the input port and the output port. The signal path includes a first section coupled to the input port and having a first passband, a second section coupled to the output port and having a second passband and a Josephson junction coupling element for parametric coupling between the first and second section. The Josephson junction coupling element is coupled to and interposed between the first section and the second section. The Josephson junction coupling element is configured such that, in response to the input port receiving a first signal at a first frequency lying within the first passband and the Josephson junction coupling element receiving a pump tone, the Josephson junction coupling element converts the first signal into a second signal with a second frequency lying within the second passband.
