A scalable control system for a superconducting adiabatic quantum optimization processor

Abstract

We have designed, fabricated and operated a scalable system for applying\nindependently programmable time-independent, and limited time-dependent flux\nbiases to control superconducting devices in an integrated circuit. Here we\nreport on the operation of a system designed to supply 64 flux biases to\ndevices in a circuit designed to be a unit cell for a superconducting adiabatic\nquantum optimization system. The system requires six digital address lines, two\npower lines, and a handful of global analog lines.\n
