In this paper,we propose a solution based on four-qubit Aharonov state to an old problem by using the property of congruence.The proposed scheme may realize the broadcast among four participants,therefore,it makes progress to the three-party broadcast realized previously.Using pairwise quantum channels and entangled qubits,the detection between these players also can be accomplished.Finally,the feasibility of the protocol and the analysis of security are illustrated.
