Remote State Preparation

Quantum information is a new subject, which was born in the twentieth century. Quantum information includes quantum communication and quantum computation, which has the potential to be widely used in future. Because it's characteristic of quantum mechanics, such as quantum superposition, entanglement, and quantum coherence, quantum information demonstrates its development in future. After the appearance of quantum information, more and more scientists pay attention to it. Under the effort, quantum information makes a great progress in theory and experiment.First, the fundament of quantum mechanics is described. Second, we introduce the theory, method and the result about many quantum communication protocols. Finally, we study the remote state preparation of one particle state, and the remote preparation of two-particle entangled state. After local operation implemented by the sender, she needs to perform the single particle measurement for three times. No matter what state the sender has got, the receiver can obtain a state which can be reverted to original state. Hence, the successful probability is improved.
