Quantum teleportation enables the secure transfer of unknown quantum states between remote users and is a key technology in quantum information science. Networks based on continuous-variable entangled states can extend both the user capacity and the transmission distance of quantum teleportation. This paper analyzes quantum teleportation network schemes based on three types of continuous-variable entangled states (EPR entangled state, GHZ entangled state, and linear cluster entangled state). The results show that due to the correlation properties of different types of entangled states, different quantum teleportation networks have advantages in terms of fidelity, transmission distance, and quantum resource consumption of quantum teleportation. For low-error-rate applications such as quantum computing, EPR states provide the highest fidelity. When parallel teleportation of multiple states is required, networks based on EPR or cluster entangled states provide the necessary throughput performance. In scenarios where quantum resources are severely limited, the GHZ-based teleportation protocols minimize the number of entangled modes while preserving acceptable fidelity. For applications demanding controlled teleportation, both GHZ and cluster states supply the essential multi-party correlations. Notably, cluster states offer a practical trade-off between fidelity and resource overhead, rendering them attractive for certain implementations. This study provides a reference for the design of multi-user metropolitan quantum teleportation networks.
