contents We consider an inhomogeneous XX spin chain which interpolates between the Krawtchouk one with perfect state transfer and the homogeneous XX chain. This model can be exploited in order to perform state transfer of a qubit with sufficiently good fidelity. The advantage of this model with respect to the Krawtchouk chain is that while it achieves efficient state transfer, the coupling strengths are capped and do not become excessively large as the number of sites grows.
