document: Cooperative three - and four-player quantum games A cooperative multi-player quantum game played by 3 and 4 players has been studied . A quantum superposed operator is introduced in this work which solves the non-zero sum difficulty in previous treatments . The role of quantum entanglement of the initial state is discussed in detail
