Abstract
Communicating a quantum state remotely is possible by Remote State Preparation. Sender Alice create a pure state known to her and help the receiver Bob to securely prepare the state remotely instead of sending the physical quantum state. To successfully perform this protocol the sender and the receiver must share Einstein-Podolsky-Rosen (EPR) state and have access to an authenticated classical channel. The sender and the receiver must be sharing an entangled bit for each state the sender wishes to prepare at the receiver’s location. In this paper we introduce a protocol to create and distribute the required entangled pairs between the communicating parities. A trusted source of EPR states will provide the necessary entangled states required to the sender and the receiver. The distributed EPR state will be used between the communicating parties to create secret keys by using remote state preparation protocol. The proposed protocol will provide unconditional security and any attacking attempt will be discovered due to the disturbance in the states.
