RT Journal Article T1 On the power of quantum entanglement in multipartite quantum XOR games A1 Junge, Marius A1 Palazuelos Cabezón, Carlos AB In this paper we show that, given k≥3, there exist k-player quantum XOR games for which the entangled bias can be arbitrarily larger than the bias of the game when the players are restricted to separable strategies. In particular, quantum entanglement can be a much more powerful resource than local operations and classical communication to play these games. This result shows a strong contrast to the bipartite case, where it was recently proved that the entangled bias is always upper bounded by a universal constant times the one-way classical communication bias.
