Perspectives of quantum annealing: Methods and implementations. (arXiv:1903.06559v1 [quant-ph])

Quantum annealing is a computing paradigm that has the ambitious goal of
efficiently solving large-scale combinatorial optimization problems of
practical importance. However, many challenges have yet to be overcome before
this goal can be reached. This perspectives article first gives a brief
introduction to the concept of quantum annealing, and then highlights new
pathways that may clear the way towards feasible and large scale quantum
annealing. Moreover, since this field of research is to a strong degree driven
by a synergy between experiment and theory, we discuss both in this work. An
important focus in this article is on future perspectives, which complements
other review articles, and which we hope will motivate further research.
