摘要

Information transfer between different nodes, particularly parallel information transfer, is fundamental to the realization of quantum networks. In this paper, we propose a scheme for implementing quantum information parallel transfer that utilizes multimode cat state encoding within a cavity-magnon system. The quantum information parallel transfer module consists of four cavities, each containing a YIG sphere. Our findings indicate that by adjusting the coupling strength and detuning between the magnons and the cavities, the encoded information can be transferred from one pair of cavities to another with high fidelity. The model presented in this study has the potential to serve as a framework for the development of ring networks or one-dimensional cavity chain structures.
