This document provides an overview of quantum annealing and its applications. Quantum annealing can be used to find the optimal solution to complex optimization problems much faster than classical computers. It does this by acting on problems simultaneously rather than sequentially. The Digital Annealer, a quantum-inspired annealing machine, can currently solve certain problems faster than traditional simulated annealing on classical hardware. Potential applications discussed include logistics routing, portfolio optimization, molecular modeling, and acoustic design optimization.
