Photonics technology has recently been involved in several research works on artificial intelligence, thanks to its ease of use, robustness and tunability. In particular, single-photon based experiments in decision making situations have sparked interest for using other quantum states of light as a new resource to be used in social situations such as the Competitive Multi-Armed Bandit. In this work we experimentally implement the 2-arms 2-players situation using either polarization-entangled photon pairs or polarized photon pairs, using polarization as a degree of freedom for decision tuning. Equality, high individual and common outcome as well as low conflict of decision are observed with entangled photons, as well as robustness against selfish or greedy action success. One-sided autonomous polarization alignment scheme is also demonstrated, providing isolated alignment protocol.
