In this paper, we discuss a quantum conference protocol whose purpose is to establish some means of sharing quantum information between the participators. This is accomplished by utilizing a single quantum entanglement resource which connects the parties involved in the protocol along with a controller whose role is of supervision. We consider three parties in different locations who exchange two different non-maximally entangled Bell states and a single qubit amongst themselves. These three states are known to three different parties, respectively, but possessed by none of them. The present protocol falls within the category of remote state preparation protocols. We study the effect of noise on our otherwise perfect protocol. Further, we discuss a scheme for the generation of the quantum channel we use in this protocol.
