| Abstract | We investigate the quantum coalition in an N-player quantum minority game proposed by Benjamin. N players share an initial entangled state and the measure of entanglement of the initial state is p. The coalition size is n (n < N). When N is odd and when N is even with the restricted condition $n\leq \frac {N}{2}$ , we find a best quantum strategy which can make the expected payoff of each coalition player reach the maximal value in this paper. We compare the expected payoffs of the coalition players before and after the best coalition, and get that whether the players coalition or not is related to p when N is even; when N is odd, the expected payoff can always be improved by coalition which is independent of p. This result provides a theory basis for the choice of the initial state in a minority game. Moreover we propose a quantum minority game with clique-wise entanglement state which can make the expected payoff reach the upper limit and reduce the possibility of coalition. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
