We have designed, fabricated and operated a scalable system for applyingindependently programmable time-independent, and limited time-dependent fluxbiases to control superconducting devices in an integrated circuit. Here wereport on the operation of a system designed to supply 64 flux biases todevices in a circuit designed to be a unit cell for a superconducting adiabaticquantum optimization system. The system requires six digital address lines, twopower lines, and a handful of global analog lines.
