A remote control scheme on setting up quantum communication channel between three legitimate participants by using only linear optical elements and photon detectors was presented. In the theoretical scheme, the two partially entangled coherent states are utilized as the quantum channel lining three remote users (Alice, Bob and Clara), Wherein, Alice is the controller, Bob and Clara were the users. First, Alice establishes the quantum communication channels and Bob and Clara, respectively (equivalent the telecommunications to establish contact with each user). When there is a direct confidential communications needs between Bob and Clara, they send a request to the Alice through a classical channel. Alice (equivalent the operator) then makes a measurement of the number of photons on own particles, respectively. The secure quantum channel between Bob and Clara was successfully established. It was proved that, although the system is designed for two uses systems, but for multiusers systems, it is still reasonable.
