Proliferation of superconducting quantum technology is limited by the scalability of such systems. Networking physically separated quantum processors is seen as a potential solution to the scalability problem. We previously proposed a microwave-millimeter four-wave mixing transduction scheme, which potentially provides a way to link quantum systems through a channel at liquid helium temperatures (4 K). In this work, we present a design methodology and measurements of a superconducting device that supports two independent modes separated by 55 GHz.
