Current driver system

A current driver system comprising:

• a current source configured to provide a source current to a transition node;
• and
• a Josephson latch coupled to the transition node and comprising:
• a plurality of Josephson junction stages being configured to conduct the source current from the transition node as a respective plurality of bias currents in a deactivated state of the Josephson latch;
• and
• a plurality of current distribution stages each comprising a bias inductor, the plurality of current distribution stages being configured to conduct a respective plurality of portions of the bias current to the respective plurality of Josephson junction stages, the bias inductor associated with a first one of the plurality of current distribution stages has an inductance that is less than the bias inductor associated with the remaining at least one of the plurality of current distribution stages;
• wherein the Josephson latch is configured to activate in response to the bias current and a trigger pulse to switch the plurality of Josephson junction stages to a voltage state to conduct at least a portion of the source current from the transition node as an output current to a load in response to activation of the Josephson latch.
