Fig. 3: Solving time of the solvers for given QUBO problems.
From: Quantum annealing for combinatorial optimization: a benchmarking study

The solving time of (a) the classical and quantum solvers and (b) the classical solvers (SA, SD, and TS) for small QUBO problems. Quantum solvers do not scale in solving time as the problem size increases, which is a great advantage over classical counterparts.
