Quantum refereed game space of this SPD is exponential (from the tensor product states) in formula_1, and the SDP has a size polynomial in the dimension of its input and output space. Since there are efficient algorithms that can solve SDP in polynomial-time, it follows that QRG ⊆ EXP. Quantum refereed game Quantum refereed game in quantum information processing is a class of games in the general theory of quantum games. It is played between two players, Alice and Bob, and arbitrated by a referee. The referee outputs the pay-off for the players after interacting with them for a fixed number of rounds,
