Dynamic programming in economics on a quantum annealer

open access: yesQuantitative Economics, Volume 17, Issue 1, Page 1-37, January 2026.
We introduce novel algorithms for solving dynamic programming problems in economics on a quantum annealer, a specialized quantum computer used for combinatorial optimization. Quantum annealers begin in a superposition of all states and generate candidate global solutions in milliseconds, regardless of problem size.
