Abstract: We propose a strategy for perfect state transfer in spin chains based on theuse of an unmodulated coupling Hamiltonian whose coefficients are explicitlytime dependent. We show that, if specific and non-demanding conditions aresatisfied by the temporal behavior of the coupling strengths, our model allowsperfect state transfer. The paradigma put forward by our proposal holds thepromises to set an alternative standard to the use of clever encoding andcoupling-strength engineering for perfect state transfer.
