A scalable control system for a superconducting adiabatic quantum optimization processor

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

  1. It’s been pretty good. It seems like this is the first idea for solving the “sea of qubits” problem that has been implemented and works. It can potentially be applied to other multi-qubit architectures as well (possibly even as component of a gate model control system). In addition this is the first major publication using chips fabricated using the D-Wave foundry and people are really interested in comparing our fab to the incumbent superconducting fabs.
