Abstract: Quantum annealing (QA) is a heuristic optimization method which is analogous to simulated annealing (SA), but which involves tuning of quantum fluctuations in the place of thermal fluctuations (temperature).  In this talk I will discuss the early origins of QA, which motivated the development of the first programmable QA processors.  The first benchmarking tests of QA led to questions and controversies, and I will discuss these and the subsequent progress in characterizing and refining QA performance.  Finally, I will cover the recent state of the art in QA for simulation and optimization as demonstrated by D-Wave, IBM, QuEra, and others.
