Abstract
We study a quantum-state transfer protocol across a 1D XY spin-1/2 channel featuring on-site magnetic field distribution following the aperiodic Sarma potential. The scheme is based upon weakly connecting the sender and receiver to the channel at each end. Our results show that such aperiodicity allows for high-fidelity performance as a band of extended states near the band center is created and the outer parts of the system are properly tuned with it. We also evaluate the generation of bipartite entanglement shared among the communicating parties.
