Quantum annealing (QA) is a quantum algorithm that can be realized at-scale using existing superconducting circuit fabrication technologies and it can be applied to a wide range of commercially-relevant computation problems. State-of-the-art QA processors contain an amalgamation of single flux quantum (SFQ)-based digital circuits, high bandwidth microwave components, and flux qubits, thus employing a wide range of superconducting devices for a common purpose. Lessons learned from this effort are expected to have significant practical implications for the broader scope of future superconducting-based quantum technologies beyond QA. This lecture consists of a brief review of current state-of-the-art QA technology, a comparison of today's QA technology to other nascent quantum computing implementations, and a survey of efforts that are underway to realize next-generation QA-related technologies using superconducting circuits.
