Magnon state transfer in memory environment

Abstract Quantum state transfer (QST) is one of the most prominent protocols in quantum information processing and quantum state engineering. In this paper, we propose an analytical framework that incorporates non-Markovian memory effects to investigate QST between magnons. We show that QST can be implemented with high efficiency by using the Ohmic spectral density. In addition, we find that, adjustable strong cavity-magnon coupling, as a major characteristic of cavity magnetic systems, not only modulates the strength of the non-Markovian effects but also further enhances the QST.
