Summary:
Collective decision-making is important in recent information and communication systems. Therein, decision conflicts among multiple agents inhibit maximizing the potential utilities of the total system under study. It has been known that quantum processes can realize conflict-free joint decisions by utilizing entanglement of photons or quantum interference of orbital angular momentum of photons among two agents. However, the resultant joint decisions always result in a symmetric manner. Although this is a good aspect in view of ensuring equality, it is not sufficient to reduce disparities. Indeed, various forms of problematic inequalities are observed nowadays, such as educational disparity and gender gap, where preserving existing equality seems insufficient. In this study, we theoretically and numerically demonstrate conflict-free and asymmetric collective decision-making by utilizing entangled photons or quantum interference of photons carrying OAM. Whereas the asymmetry is indeed possible, photon loss is inevitable in the proposed models. The achievable range of asymmetry is analytically clarified.
