US Patent 10122350 Josephson transmission line (JTL) system

One embodiment describes a Josephson transmission line (JTL) system. The system includes a plurality of JTL stages that are arranged in series. The system also includes a clock transformer comprising a primary inductor configured to propagate an AC clock signal and a secondary inductor arranged in a series loop with at least two of the plurality of JTL stages. The clock transformer can be configured to propagate a single flux quantum (SFQ) pulse to set a respective one of the plurality of JTL stages in response to a first phase of the AC clock signal and to reset the respective one of the plurality of JTL stages in response to a second phase of the AC clock signal that is opposite the first phase.
