Abstract

In order to solve the problem for arbitrary two-qubit quantum communication, this paper firstly gave the construction methods of five- and seven-particle entangled states, and provided their quantum circuit diagrams. Next, taking this entangled five-particle state as quantum channel, this paper proposed a controlled teleportation protocol for an arbitrary two-particle unknown quantum state. Under the control of the supervisor Charlie, Alice carried out four-particle projective measurement and classical communication, and Bob could successfully reconstruct an arbitrary two-particle entangled state with 100% probability by using simple unitary transformation. Finally, the paper put forward a joint controlled remote preparation scheme for an arbitrary two-particle entangled state by using the seven-particle entangled state as quantum channel. In this scheme, the sender Alice constructed a measurement basis with some information of the prepared state, which were had by her. The sender Bob used feed-forward measurement strategy, and the receiver Diana, with the help of the supervisor Charlie, could restore the original state deterministically by simple unitary transformation.
