    "abstract": "The idea of quantum state storage is generalized to describe the coherent\ntransfer of quantum information through a coherent data bus. In this universal\nframework, we comprehensively review our recent systematical investigations to\nexplore the possibility of implementing the physical processes of quantum\ninformation storage and state transfer by using quantum spin systems, which may\nbe an isotropic antiferromagnetic spin ladder system or a ferromagnetic\nHeisenberg spin chain. Our studies emphasize the physical mechanisms and the\nfundamental problems behind the various protocols for the storage and transfer\nof quantum information in solid state systems.",
