In this two-part talk, we introduce a novel method that utilizes a two-mode transmission line doped with Josephson junctions. A traveling-wave pump applied on one mode activates a directional photon conversion process on the second mode, ultimately leading to circulation within the circuit. Our approach offers the advantage of broad tunability, high isolation, and is compatible with traveling-wave amplification. In this first part, I will present the working principle of our device.
