Keywords:orbital angular momentum, entanglement, decision making

We demonstrated a system that achieves probabilistic selection with orbital angular momentum (OAM) of light. It achieves selection from more than two options and can be applied for solving multi-armed bandit problems. We also demonstrated that OAM entangled photons can be applied for solving competitive multi-armed bandit problems with fairness and achieving high total reward under no direct communications between players.
