Quantum annealing is a meta-heuristic algorithm for finding the global minimum of a given objective function over a given set of candidate solutions by using a process of quantum fluctuations.

How does a quantum annealer work?

D-Wave’s system works through a process called quantum annealing.This starts with Put the system’s qubits at an absolute energy minimumFrom there, the hardware gently changes the configuration of the system so that its energy landscape reflects the problem that needs to be solved.
