The Advantage2(TM) system is D-Wave's sixth commercially available quantum computer, with a qubit degree of 20 and significantly greater energy-scale than the Advantage(TM) system, its predecessor. At its core is the quantum processing unit (QPU), a superconducting integrated circuit (IC) built from more than 1 million Josephson junctions. We present the underlying IC design approach, introducing a trade-off between qubit degree and energy-scale informing the architectural optimization of the qubit fabric on the QPU. We describe the scalable on-chip control and readout circuitry built from superconducting design elements like superconducting quantum interference devices (SQUIDs), quantum flux parametrons (QFPs), and resonators. We show how our design choices lead to increased performance on computational problems. Finally, we show how to use the on-chip superconducting control infrastructure to perform digital operations on the qubit fabric of the Advantage2 QPU.
