Abstract

This paper presents a systematic approach for implementing arbitrary unknown multi-qubit state sharing by multiple agents and its generalization to independent state joint sharing collaborated with multi control agents in quantum deterministic and probabilistic networks. To supervise all independent processes of quantum state sharing, each control agent needs to hold and measure only one particle. This scheme can be used in multi-layer quantum networks to monitor the data flow in secured communication. The performance analysis shows that less qubit resources and less amount of classical communication information are required compared with existing schemes.
