Effective propagation of information among multiple users is the purpose of realizing large-scale quantum communication networks.In this paper,multicast protocols for any single,two and three qubits with real amplitude and complex phase information are presented.They were realized using a composite of Greenberger-Horne-Zeilinger states as shared channels.Joint remote state preparation was the main method for completing quantum multicast.At the same time,quantum state tomography of the schemes was carried out on the IBM Quantum platform.The obtained states were compared with the target states by fidelity.The analysis of communication efficiency and noise effects shows that our protocol has advantages in the case of complex coefficients.
