Systems, methods and apparatus for digital-to-analog conversion of superconducting magnetic flux signals

A superconducting programmable device comprising:

• a plurality of programmable elements;
• and
• an addressable superconducting flux digital-to-analog converter (DAC) structure, the addressable superconducting flux DAC structure comprising:
• a first plurality of DACs addressable by a first column line, each of the DACs in the first plurality of DACs addressable by a respective one of a number of bit lines;
• and
• at least a second plurality of DACs addressable by a second column line, each of the DACs in the second plurality of DACs addressable by a respective one of the number of bit lines,
• wherein each of the DACs includes at least one respective flux divider network and at least two respective superconducting quantum interference devices (SQUIDs), each of the at least two SQUIDs configured to inductively couple magnetic flux quanta to a respective superconducting inductor in the at least one flux divider network;
• wherein each DAC in the addressable superconducting flux DAC structure is configured to administer signals to at least one programmable element in the plurality of programmable elements.
