Description
Summary:The goal of this paper is to further study multi-party multicast quantum communication of arbitrary two-qubit states. We first construct 9-qubit entangled channel by Hadamard gates and controlled-NOT gates and then, propose a new deterministic four-party scheme for multicast-based remote state preparation of two different two-qubit states, where the different arbitrary complex coefficient two-qubit states are transmitted synchronously from one sender to two spatially separated receivers under the control of the supervisor. In order to meet the needs of communication in noisy environment, we propose another three-party scheme for multicast-based remote state preparation of special complex coefficient two-qubit states by using the eight-qubit partially entangled state as the quantum channel. Finally, we discuss the feasibility of physical experiment, the security and the control power of the controller of the presented schemes.
