US Patent 11476842 Superconducting current source system

One example describes a superconducting current source system comprising a linear flux-shuttle. The linear flux-shuttle includes an input and a plurality of Josephson transmission line (JTL) stages. Each of the JTL stages includes at least one Josephson junction, an output inductor, and a clock input. The linear flux-shuttle can be configured to generate a direct current (DC) output current via the output inductor associated with each of the JTL stages in response to the at least one Josephson junction triggering in a sequence in each of the JTL stages along the linear flux-shuttle in response to receiving an input pulse at the input and in response to a clock signal provided to the clock input in each of the JTL stages.
