Abstract

We have designed, fabricated and operated a scalable system for applying independentlyprogrammable time-independent, and limited time-dependent flux biases to controlsuperconducting devices in an integrated circuit. Here we report on the operation of asystem designed to supply 64 flux biases to devices in a circuit designed to be a unit cell fora superconducting adiabatic quantum optimization system. The system requiressix digital address lines, two power lines, and a handful of global analog lines.
