摘要：
Controlled dense coding via multi-particles GHZ state and multi-particles GHZ-class state are exploited in this letter. The quantum channel and the amount of information between the senders and the receivers are controlled by the supervisor via his local measurement. The amount of information is determined by Charlie's measurement in the former case of GHZ state, and also by the coefficients of the original GHZ-class state in the latter case.
