Transferring Multi-Dimensional Quantum States and Preparing Quantum Networks in Cavity QED

fn this paper we propose a scheme for transferring quantum states and preparing quantum networks.Compared with the previous schemes,this scheme is more efficient,since three or four-dimensional quantum states canbe transferred with a single step and information interchange of three-dimensional quantum states can be realized,whichis a significant improvement,ft is based on the resonant interaction of a three-mode cavity Geld with an atom.As aconsequence,the interaction time is shortened greatly.Furthermore,we give some discussions about the feasibility ofthe scheme.
