Perfect information transfer in spin chains and perfect state control in quantum chains
Based on analysis of neighbor-coupled spin chains, a method to get the parameters of the spin chains for perfect information transfer is given, and all analytical solutions are obtained by using Groebner basis analysis. The method is suitable to get the parameters of pulse-driven perfect state control in multilevel chains. The results can be used to analyze structures of the solutions or find particular parameters with optimal properties.
