    "abstract": "We generalize an already proposed protocol for quantum state transfer to spin\nchains of arbitrary spin. An arbitrary unknown $d-$ level state is transferred\nthrough a chain with rather good fidelity by the natural dynamics of the chain.\nWe compare the performance of this protocol for various values of $d$. A\nby-product of our study is a much simpler method for picking up the state at\nthe destination as compared with the one proposed previously. We also discuss\nentanglement distribution through such chains and show that the quality of\nentanglement transition increases with the number of levels $d$.",
